Answer:
Step-by-step explanation:
Given: Kite WXYZ
Prove: That at least one of the diagonals of a kite decomposes the kite into 2 congruent triangles.
A diagonal is a straight line from one vertex to another of a given shape or figure.
Considering diagonal WY of the kite,
<WYZ ≅ <WYX (diagonal WY is the bisector of <Y)
<ZWY ≅ <XWY (diagonal YW is the bisector of <W)
WZ ≅ WX (congruent property)
YZ ≅ YX (congruent property)
Thus,
ΔWYZ ≅ ΔWYX (Angle-side-Angle congruent property)
Therefore, the given kite can be decompose into 2 congruent triangles (ΔWYZ and ΔWYX).
