2 Vertical Angles – each of the pairs of opposite angles made by two intersecting lines. Rail Road Crossing Sign This picture would be a real world example of vertical angles, and not only is there one but there is two. Since the two “lines” are intersecting, it will create two pair of vertical angles that will always be congruent. https://www.google.com/sea rch?q=geometry+in+the+real +world&biw=1280&bih=622 &source=lnms&tbm=isch&sa =X&ei=ZQksVfqLAsmMNpDzg dgM&sqi=2&ved=0CAYQ_AU oAQ#tbm=isch&q=vertical+a ngle+in+the+real+world&img rc=oeaAhPwY6fY1jM%253A% 3B- YtnRZh4fqJ5FM%3Bhttp%253 A%252F%252Fcx.aos.ask.co m%252Fquestion%252Faq%2 52F700px- 700px%252Fexamples- vertical-angles-real- life_e45718bd19f1931b.jpg% 3Bhttp%253A%252F%252Fw ww.ask.com%252Fmath%252 Fexamples-vertical-angles- real-life- e45718bd19f1931b%3B700% 3B394 Vertical angles are always congruent 1 2 3 4 <1 and <3 are vertical <4 and <3 are vertical

3 Vertical Angles – each of the pairs of opposite angles made by two intersecting lines. Acute Triangle - A triangle that has all angles less than 90° Pool Ball Holder https://www.google.com/s earch?q=real+life+example +of+an+acute+triangle&es pv=2&biw=1280&bih=578 &source=lnms&tbm=isch&s a=X&ei=ZhAsVeTqIsj2sAXM roOoBg&ved=0CAYQ_AUoA Q#imgrc=RJmWSPlHBZ0vC M%253A%3BLl6I94- 3Ul96QM%3Bhttps%253A %252F%252Fmrsbuckhoffsc lass.wikispaces.com%252Ffi le%252Fview%252Fequilat eral.jpg%252F237182230% 252Fequilateral.jpg%3Bhttp s%253A%252F%252Fmrsbu ckhoffsclass.wikispaces.co m%252FMath%252Bin%25 2BReal%252BLife%3B240% 3B180 This picture is a real life example of an acute triangle because all of the angles will add up 180 degrees but none of them will be more than 89 degrees. Acute triangles will always have three acute angles.

4 Vertical Angles – each of the pairs of opposite angles made by two intersecting lines. Obtuse Triangle – A triangle that has one angle greater than 90 degrees The triangle would be an example of an obtuse angles because the very top angle is greater than 90 degrees.

5 Vertical Angles – each of the pairs of opposite angles made by two intersecting lines. Right Triangle – A triangle that has one measure of 90 degrees Sandwich Half https://www.google.com/sear ch?q=real+world+example+of +an+obtuse+triangle&biw=12 80&bih=622&tbm=isch&imgil =oETHyLwKMunobM%253A% 253BftvQJuoYPd54OM%253B http%25253A%25252F%2525 2Fmath.tutorvista.com%2525 2Fgeometry%25252Fobtuse- triangle.html&source=iu&pf= m&fir=oETHyLwKMunobM%2 53A%252CftvQJuoYPd54OM% 252C_&usg=__3AoUnAR_2Ho 0PSEXVDkh90dWTzw%3D&ve d=0CCcQyjc&ei=6BEsVa7EHcz RsAXr2IGIBw#tbm=isch&q=re al+world+example+of+a+right +triangle&spell=1&imgrc=C9S B2BoJ-- lq7M%253A%3B4jlQL0oKKxnS BM%3Bhttp%253A%252F%25 2Fimages.tutorcircle.com%25 2Fcms%252Fimages%252F113 %252Fright-triangle- example.png%3Bhttp%253A% 252F%252Fmath.tutorcircle.co m%252Fgeometry%252Fright- triangle.html%3B218%3B238 This picture is a real world example of a right triangle because by the eye one of the angles looks to be 90 degrees. A right triangle will always have one angle that measures exactly 90 degrees.

6 Vertical Angles – each of the pairs of opposite angles made by two intersecting lines. Equilateral Triangle - A triangle with all three sides of equal length. All the angles are 60° Pool Ball Holder https://www.google.com/s earch?q=real+life+example +of+an+acute+triangle&es pv=2&biw=1280&bih=578 &source=lnms&tbm=isch& sa=X&ei=ZhAsVeTqIsj2sAX MroOoBg&ved=0CAYQ_AU oAQ#imgrc=RJmWSPlHBZ0 vCM%253A%3BLl6I94- 3Ul96QM%3Bhttps%253A %252F%252Fmrsbuckhoffs class.wikispaces.com%252 Ffile%252Fview%252Fequil ateral.jpg%252F23718223 0%252Fequilateral.jpg%3B https%253A%252F%252F mrsbuckhoffsclass.wikispa ces.com%252FMath%252B in%252BReal%252BLife%3 B240%3B180 This picture would be a real life example of a equilateral because all of the angles are acute, and they look to be 60 degrees each. An equilateral triangle will always be considered an isosceles triangle.

7 Vertical Angles – each of the pairs of opposite angles made by two intersecting lines. Isosceles Triangles – A triangle that has two equal measures https://www.google.com/sear ch?q=real+world+example+of+ an+obtuse+triangle&biw=1280 &bih=622&tbm=isch&imgil=oE THyLwKMunobM%253A%253B ftvQJuoYPd54OM%253Bhttp% 25253A%25252F%25252Fmath.tutorvista.com%25252Fgeome try%25252Fobtuse- triangle.html&source=iu&pf=m &fir=oETHyLwKMunobM%253 A%252CftvQJuoYPd54OM%25 2C_&usg=__3AoUnAR_2Ho0PS EXVDkh90dWTzw%3D&ved=0 CCcQyjc&ei=6BEsVa7EHczRsAX r2IGIBw#tbm=isch&q=real+wo rld+example+of+an+isosceles+ triangle&imgrc=BNeULZ9BHvY QTM%253A%3BLl6I94- 3Ul96QM%3Bhttps%253A%25 2F%252Fmrsbuckhoffsclass.wik ispaces.com%252Ffile%252Fvi ew%252Fisosceles.jpg%252F23 7186492%252Fisosceles.jpg%3 Bhttps%253A%252F%252Fmrs buckhoffsclass.wikispaces.com %252FMath%252Bin%252BRe al%252BLife%3B240%3B180 Clothes Hanger This would be a real life example of an isosceles because two of the angles have the same measurement, while the other angle is a different measurement. An isosceles triangle will always have two of the same angle measurements.

8 Vertical Angles – each of the pairs of opposite angles made by two intersecting lines. Scalene Triangle – A triangle that has no equal angle measures https://www.google.c om/search?q=real+lif e+example+of+a+scal ene+triangle&espv=2 &biw=1280&bih=622 &source=lnms&tbm=i sch&sa=X&ei=Y1wtVY OgNYO- ggSlgITgAw&ved=0CA YQ_AUoAQ#imgrc=1k 6gU2ggSh9VIM%253 A%3BZAzxBNHL1OW RJM%3Bhttp%253A% 252F%252F4.bp.blogs pot.com%252F- DEUVNNmhzlk%252F TptbtzkDIQI%252FAA AAAAAAADo%252Foe JEDOqPYik%252Fs400 %252FDSCF6429.JPG %3Bhttp%253A%252 F%252Femiliefrazier. blogspot.com%252F% 3B400%3B300 Protractor/ruler This would be an example of a real life scalene triangle because by the eye, you can see that none of the triangles angles are exactly the same measure. A scalene triangle will never have any of the same angle measures.
