What is the length of XY?
xeze [42]

Answer:

( C ) 20 inch

Step-by-step explanation:

AB=28 inch ( given )

AP=26 inch ( given )

since that xy bisects and its perpendicular to AB and CD

then AX=48/2 = 24 inch

so by using Pythagoras theorem

then  26 squared - 24 squared = 10 inch

so XD+YD= 10 +10 =20 inch

Question 6 of 10
Verizon [17]

Answer:

<em><u>True.</u></em>

Step-by-step explanation:

We have to tell about the statement true or false

Two triangles that have the same side length will always be congruent

The SSS congruency rule states that if all three sides of one triangle are equal to corresponding three sides of another triangle, then the triangles are congruent.

∴ we say that when the sides are the same then the triangles are congruent.

<u><em>Hence, the statement is true.</em></u>

Because the definition of a congruent triangle is a triangle with every side of same length.
