Question

construct a right-angled triangle, where the hypotenuse is 5 cm and one of the arm measuring 4cm

Answer 1

Draw base BC = 4cm
From end B draw 90 degrees using rounder...extend the line vertically upwards
From end of C cut an arc of 5cm on the vertical line of 90 degrees
Mark the point A
thus, triangle ABC is the required right-angled triangle

The diagram below is a rough diagram of how ur construction will actually look
