Question

Prove that the lengths of altitudes drawn to equal sides of an isosceles triangle are also equal. (i) angle TRQ = angle SQR? (ii) If angle TRQ = 30°, find the base angles of the triangle PQR. (iii) Is triangle PQR an equilateral triangle? ​

Answer 1

Answer:

∆ABC = ∆EDF

Step-by-step explanation:

AB = DE = 3cm

BC= DF = 3.5cm

AC= EF =4.3cm

∆ABC = ∆EDF
