Question

Construct a triangle ABC such that BC = 6.5 cm and angle B = angle C = 70°. Draw all possible lines of symmetry.​

Answer 1

To construct triangle ABC follow the below steps:

1. Construct a line segment of length 6.5cm and name it as BC.
2. Now place the protractor at point B and measure the angle 70° and mark a line measuring 70°.
3. Similarly place the protractor at C and measure an angle 70° and draw a line at an angle 70°.
4. Now the intersection of both the lines is the point A.
5. Mark the intersection of both lines as A.
6. Triangle ABC is now constructed.
