Question

19) Construct a triangle with base of length 7.5 cm, the difference of the other two sides 2.5 cm and
one base angle of 45°.Justify the construction.​

Answer 1

Step-by-step explanation:

1: Draw the base BC 7.5 cm and at point B make an angle XBC of 45 degree.

2: Cut line segment BD equal to AC - BC (4cm) from line BX extended on opposite side of BC.

3: join DC and draw perpendicular bisector say PQ and DC.

4: let PQ intersect BX at A. Join AC.

Thus, ABC is the required triangle.
