Question

XY
1. In A POR, X is the midpoint of QR.
and XZ
are altitudes from X on PQ and
PR respectively. If XY = XZ, then prove that
A PQR is an isosceles triangle.​

Answer 1

Step-by-step explanation:

join y and z to make an isosceles triangle. so angle y equals angke z.by aaa corrolary triangle pyz ~ por.

as angle y equals angle z, andl o equals angle r.

therefore pr equals po. thus por is an isosceles triangle.
