Question

Construct an equilateral triangle each of whose sides measures 6.2 cm. Measures each one of its angles.

Answer 1

Steps of construction:

1. Draw a line segment AC = 6.2 cm.

2. With A as a center and radius 6.2 cm, draw an arc.

3. With C as a center and radius 6.2 cm, draw another arc, cutting the previous arc at B.

4. Join AB and CB.

Then, ΔABC is the required equilateral triangle.

5. When we will measure all the angles of triangle by protractor, then all angles are equal to 60^o.
