Question

In A ABC, the perpendicular from vertices A and B on their opposite sides meet (when produced)
the circumstances of the triangle at points D and E, respectively. Prove that arc CD=CE.

Answer 1

Answer:

Given: In ΔABC, the perpendiculars from vertices A and B on their opposite sides meet (when produced) the circumcircle of the triangle at points D and E respectively.

To prove: Arc CD = Arc CE

Construction: Join CE and CD
