Question

Construct a right trangle abc such that bc = 4cm and the hypotenuse makes an angle of 30 degre at



b. Veify that ab=2ac.

Answer 1

STEPS OF CONSTRUCTION :-

• Draw a line BC = 4c m
• From vertex B , draw a right triangle .
• From vertex C , draw an angle of 30° (using protractor or campass)
• Where the line of 90° and 30° meet ,mark that point as A
• Join AB and AC .
• We require a right triangle ABC .
• Measure AB
• Now , measure AC
• Check that AB = 2AC .
