Answer 2

b) ∆PQR is an equilateral triangle is an incorrect statement.

• Since Angle PQR is 90°, the side PR will be the hypotenuse. Due to the presence of a 90° angle, the triangle will be right-angled.
• As the given triangle is isosceles, it will have two equal sides. Concerning this, the two angles will also be the same.
• An equilateral triangle has three equal sides, which is not present in the shown triangle.
