PDF Geometry: Proofs and Postulates Worksheet - Math Plane 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) therefore, ACAB= ADAB (side-angle-side) If triangles are same, then L ABC = LABD (CPCTC)
