Question

3. (1) AABC is an equilateral triangle. From A, an altitude AD is drawn. Find measure of angle BAD.
(ii) In an isosceles APQR, PQ = PR and PT is perpendicular on QR. IF QT = 3 cm, what will be the length of TR?​

Answer 1

Step-by-step explanation:

1.

angel BAD= 45°

2.in an isosceles triangle any two sides are equal

if PT is perpendicular then

triangle PTQ=PTR

therefore QT=3cm

then TR=3cm
