Question

Let's draw two isosceles triangle PQR of different measurements. From the vertex P, draw a straight line to meet the mid-point of QR at S. Verify experimentally that PS is perpendicular to QR.​

Answer 1

Explanation:

• Let's draw two isosceles triangle PQR of different measurements. From the vertex P, draw a straight line to meet the mid-point of QR at S. Verify experimentally that PS is perpendicular to QR.​

being two isosceles triangles, the line that goes from the vertex P to the point S is nothing other than the height, the height, by definition, is perpendicular to the base
