Prove that if a quadrilateral has four equal sides and one right angle, then the quadrilateral is a square

1 answer:

3 0

So lets ABCD are the sides of the square and AB=CD, AC=BD and the Angle ABC = 90 so therefore by making a diagonal we can use the SAS or SSS congruency for two triangles, so we can prove two triangles are equal and that is why the shape is square.

A. CPCTC b. SAS c. ASA d. SSS

Lyrx [107]

a. CPCTC is your answer

CPCTC means that "Congruent Parts of a Congruent Triangle(s) are Congruent"

If ΔBRM ≅ ΔKYZ (given), then every part inside the triangle is ≅ with the corresponding side.
So, for example Line BR will be ≅ with Line KY, etc

hope this helps
