contruct a right triangle having hypotenuse of lenght 5cmand one of the acute angles of measures 45degrees


steps of constructions:
1. draw a horizontal line through A.
2. at the point A, draw an angle of 45 deg.
3. from the point A cut an arc of 5 cm let it intersect the line at B.
4. from the point B , draw the perpendicular BC , intersect  the line drawn in step 1.
thus ACB is a right angle triangle , right angle at C
hypotenuse AB = 5 cm

hope this helps you
