Construct a right angel abc such that BC 4cm and hypotenuse is 30 at b

Answer 1

if you mark off a length of 4, you can easily construct a length of 30.

Double the 4 to 8, double the 8 to 16, double the 16 to 32.

Halve the 4 to get 2, and subtract that from the 32.

Now construct the leg BC, and the right angle at C. Then mark off a circle of radius 30 to intersect the perpendicular at C.

Answer 2

Construct the right angle triangle bc 4 cm and the hypotenuse is 30 at b vetify that ab equal to2ac
