triangle qrp is congruent to triangle yxz. what is the perimeter of triangle yxz?
what is the perimeter of triangle yxz?

6.4 inches

Step-by-step explanation:

As given triangle QRP is congruent to triangle YXZ.

where ∠Q=72°

PR =2.5 inches

∠Z=36°

XY=1.4 inches.

then  QP=YZ,PR=YZ=2.5 , QR=XY=1.4 inches,∠Q=∠Y=72°,

∠P=∠Z=36° and ∠R=∠X= 180°-36°-72°=72°(by angle sum property)

As ∠Y=∠X=72° Hence triangle XYZ is a isosceles triangle .

We know that "Sides opposite to equal angles of a triangle are equal"

⇒YZ=XZ=2.5 inches

Thus the perimeter of triangle YXZ=YX+XZ+ZY=1.4+2.5+2.5=6.4 inches.

no

Step-by-step explanation:

the properties for a parallelograms are

we can conclude that the quadrilateral is not a parallelogram because it only has one pair of opposite sides that are equal. (the dashes through the sides show they are congruent to each other)
