Similar triangles: Side - Angle - Side Definition: If a pair of coresponding sides of 2 triangles have the same ratio AND the included angles are congruent, then the triangles are similar. A DEF ratio of 2 sides are equal, & non-included angles are congruent but, triangles are not similar! Comments: Example: A ABC

Each side of square B is 9 cm. What is the ratio of the perimeters of A to B? Perimeter ratio is identical to sides ratio. perimeter of A: 24 24:36 or perimeter of B: 36 or What is the ratio of the areas of the 'squares'? Area ratio is ratio of the "squares" or area of A: 36 areaofB: 81 62: 9 36:81
Introduction to proofs: Identifying geometry theorems and postulates ANSWERS C congruent ? Explain using geometry concepts and theorems: 1) Why is the triangle isosceles? PR and PQ are radii of the circle. Therefore, they have the same length. A triangle with 2 sides of the same length is isosceles. 2) Why is an altitude? AB = AB (reflexive ...
