Point  A capital on a map would be considered an example of a “point”, because a point is a direct location on the map just as a point would be on a line.

Line  The equator represents a “line” because a line is infinitely long and straight just as a interstate typically seems to be.

Plane  A state or city on a map represents a “plane” because just like a plane, a state or city can have several different points (locations) and you can call it by one general name.

Segment  A street or road is an example of a “segment” because just like a segment, the street starts at one point and eventually ends at another location. Geometry Connection Real World Connection mages?q=tbn:ANd9G cSVmaT5RfChhujnGj Mqj00siwxrnHLv41GO 4oIklbt8_gjm9mLmZg

Ray  A interstate represents a “ray” because it starts at one point and goes on for what seems to be forever, just as a ray is infinitely long.

Collinear Points  Cars lined at a traffic light would be an example of “collinear points” because they are all in the same line/lane, just as collinear points would be.

Acute Angle  A folded seat in the car would represent an “acute angle” because it is less than 90 degrees just as an acute angle. Geometry Connection Real World Connection pted- tbn2.gstatic. com/images ?q=tbn:ANd 9GcRsgjd0o 40YEf- bakQakNIlyv E_YzBT4AZev uHTMbxAOf haEyfXzQ

Obtuse Angle  A reclining chair in the living room would represent an “obtuse angle” because it is reclined more than 90 degrees as how an obtuse angle would be.

Right Angle  The corner of a picture frame would represent a “right angle” because it is exactly 90 degrees just as a right angle.

Perpendicular Lines  A intersection would represent “perpendicular lines” roads/lines meet and form four 90 degree angles.

Complementary Angles  An example of “complementary angles” would be the flaps on an envelope measured to add up to 90 degrees from each side, just as complementary angles.

Supplementary Angles  An example of “supplementary angles” would be railroad tracks, because from every angle the railroad tracks would end up having a sum of 180 degrees just as supplementary angles would.

Vertical Angles  A pair of scissors is an example of vertical angles because the angles are opposite each other when two lines cross. They are always equal. tbn3.gstatic.com/images ?q=tbn:ANd9GcT1NIYz0d YUVam_IKRO899axoo9yt QOmCtje8c_t5AxkCH9tL cM tbn2.gstatic.com/i mages?q=tbn:ANd 9GcR_knP3gx9gb3 Z9AwMnNjEx_bna5 dGrRRec07JoE_0A vRGBxLtTbA Geometry Connection Real World Connection

Acute Triangles  The structure of the roof is an example of an acute triangle because it has all angles less than 90 degrees tbn3.gstatic.com/i mages?q=tbn:ANd 9GcTVbCFnsMDQR aUsiA6gCbVWGeT blEP6DitIIFXRSFJuR9 QxpY1KZg d- tbn1.gstatic.co m/images?q=tb n:ANd9GcQcm YZDEYjLGJ- oq9YnmFIbzL7zfI vZAiQE1_ofx- 40q-NiEyJqXg Geometry Connection Real World Connection

Obtuse Triangles  The triangles in the bridge are examples of obtuse triangles because they each have one angle greater than 90 degrees. ted- tbn1.gstatic.c om/images?q =tbn:ANd9Gc Q1fiBBeGDvo Re- vOAujaPOWb MAfzoQjvMBV MpUBwigU62y fwhAzg ed- tbn3.gstatic.co m/images?q=t bn:ANd9GcRfX lqs3Hzvvlnru1o oO9f71jlbILNpz At- fIwZKbYMiJmhL oox8Q Geometry Connection Real World Connection

Equilateral Triangles  A pool ball rack is an example of an equilateral triangle because all the same angle measurements and the same side lengths. ted- tbn1.gstatic.c om/images?q =tbn:ANd9GcT A8ob8llb66FQ gsI4zm3vxeUC _U1LgWVpziO9 pLlqQeHHke- DdGw rypted- tbn2.gstati c.com/ima ges?q=tbn :ANd9GcS Byzm0UVb 1HQ_6ZdX pxYMO5o MLGrdaW3 pG1Z32F_n 1jPZ7vaWd cA Geometry Connection Real World Connection

Isosceles Triangles tbn2.gstatic.com/i mages?q=tbn:AN d9GcSsaAhAGSHo ic_f_L__qwBBOVLo RFp3Zdue4iyQdsC 1zCJcVtDYqQ A flag is an example of a isosceles triangle because at least two sides are congruent on the triangle. Theorem: If two sides of the triangle are congruent, then two angles opposite of sides are congruent. pted- tbn1.gstatic. com/images ?q=tbn:ANd 9GcSJeRqAF dOjuMwGliir qyYjrm6aiub 0K3X7TthyAt HmoS6karm8 Hw Geometry Connection Real World Connection
