Then look for triangles that contain these angles. The diagonals of a rhombus are congruent, perpendicular, and bisect the vertex angles of the rhombus. An isosceles trapezoid has one pair of noncongruent parallel sides, a pair of congruent nonparallel sides, and two pairs of congruent angles.

What is the area of the other plate? Label the angle measures directly on the figure. The diagonals of a parallelogram bisect each other.

# Reteach Triangle Congruence

Some hikers come to a river in the woods. Two pairs of sides are congruent, because their lengths are equal. Work backward when planning a proof. The longest sides of all the sandwiches are 3 inches. Write a flowchart proof. Suggest us how to improve StudyLib For complaints, use another form.
