Question

Draw an isosceles triangle with each of equal sides of length 3 cm and the angle between them as 45°.

Answer 1

Steps of construction:

Step I: Firstly, we draw a rough sketch of triangle with given measures marked on it.

Step II: Draw a line segment AB of length 3 cm.

Step III: Draw an angle of 45° on point B and produce it to ray Y.

Step IV: With B as centre, draw an arc of 3 cm which intersects ray BY at C.

Step V: Join AC.

Thus, AABC is the required isosceles triangle.
