To explain:
Thegiven information of two triangles are congruent.
Answer to Problem 19E
Explanation of Solution
Given:
Concept used:
Two geometric figures are congruent if a rigid motion or a composition of rigid motions maps one of the figures onto other.
Calculation:
If two triangles are congruent.
So all the corresponding parts are congruent.
If all corresponding parts of two triangles are congruent.
So the triangle are congruent.
Two pairs of corresponding sides of the included angles of those sides are marked congruent.
All point on a circle are the same distance from the center
By the reflexive property of congruence
An angle bisect cuts an angle into two congruent
So, the congruence theorem can be used.
