Questions over HOMEWORK?

Skills check!

Congruent triangles have congruent sides and congruent angles.

The parts of congruent triangles that “match” are called corresponding parts.

Z

60°

R

50°

70°

T

Y

2n+10°

X

RST is congruent to XYZ. Find the value of n.Since RST is congruent to XYZ, the corresponding

parts are congruent.

60 = 2n+10

50 = 2n

n = 25

Overlapping sides are congruent in each triangle by the REFLEXIVE property

Alt Int Angles are congruent given parallel lines

Vertical Angles are congruent

Side-Side-Side (SSS) Congruence Postulate

All Three SIDES of one triangle are congruent to all three sides of the other triangle

Side-Angle-Side (SAS) Congruence Postulate

Two sides and the INCLUDED angle

On the following slides, we will determine if the triangles are congruent. If they are, write a congruency statement explaining why they are congruent. Then, state the postulate (rule) that you used to determine the congruency.
