Question

construct a triangle ABC in which angle b=60 degree angle c=45 degree and its perimeter is 11cm
​

Answer 1

Answer:

Step-by-step explanation:

Steps of Construction:

1.Draw a line segment PQ = 11 cm.( = AB + BC + CA).

2.At P construct an angle of 60° and at Q, an angle of 45°.

3.Bisect these angles. Let the bisectors of these angles intersect at a point A.

4.Draw perpendicular bisectors DE of AP to intersect PQ at B and FG of AQ to intersect PQ at C.

5.Join AB and AC (see Fig. 11.9). Then, ABC is the required triangle.
