Trigonometry By Dave & Ron

Identifying Triangles By Sides  Iscoceles  Equilateral  Scalene  Right  Iscoceles  Equilateral  Scalene  Right

Determining Isosceles  Isosceles Triangles will have 2 equal sides, and one unequal. For example, Two sides are 8meters long, And the base is 14meters

Determining Equilateral  An equilateral triangle is a triangle with all equal sides, hence the name Equilateral.

Determining Scalene  Scalene Triangle’s have no equal sides. They’re all congruent, and each angle is equal to 60º!

Determining Right Triangles  Its easy, there are 3 sides to a right triangle. The legs, which are straight, and the hypotenuse is a diagonal line. The angle of the 2 legs is ALWAYS equal to 90 degrees.

Identifying Triangles by Angles  Obtuse  Acute  Right  Obtuse  Acute  Right

Identifying Obtuse Angles  An Obtuse angle is an angle of a triangle over 90 degrees.

Identifying Acute Angles  Acute angles are tiny angles, smaller/less than 90 degrees,

Identifying Right Angles  All right triangles will have right angle the right angle as said before always has a 90 degree angle.

Special Rules/Tips & Tricks  There are a few special rules you ought to remember when dealing with isosceles and/or equilateral triangles. They are outlined below.  1. If a triangle is equilateral, it is equiangular.  2. If two angles of a triangle are congruent, they are the base angles of an isosceles triangle.  3. If a triangle is equiangular, it is equilateral.  There are a few special rules you ought to remember when dealing with isosceles and/or equilateral triangles. They are outlined below.  1.

Pythagorean Theory If you have to find the Hypotenuse: Square The Sides, And then add them, And then find the square root of your result. If youre looking for a leg, Square the Hypotenuse, And the and the leg, then just subtract the larger one to the smaller one then square your result and that’s the leg.

REVIEW! Isosceles: 2 Equal Sides Scalene: No Equal Sides Right: 90 Degree Angle Equilateral: All Equal Sides Obtuse: >90º Acute: <90º Right: 90º Isosceles: 2 Equal Sides Scalene: No Equal Sides Right: 90 Degree Angle Equilateral: All Equal Sides Obtuse: >90º Acute: <90º Right: 90º
