Question

Construct a 4 ABC in which AB = 4 cm, BC = 3 cm and AC = 5 cm. Measure <B.
What type of triangle is this?​

Answer 1

Step-by-step explanation:

Given

BC=3 cm

AC=4 cm and

AB=5 cm

Steps of Construction:

(i) Draw a line segment AB of length 5 cm

(ii) From B, using compass cut an arc of 3 cm radius

(iii) Similarly, from A again with the help of a compass, cut an arc of 4 cm bisecting the previous arc formed from point B

(iv) Now, join point C with A and B

(v) The obtained triangle is the required ΔABC

(vi) On measuring ∠ACB, we get ∠ACB=90

0

.

Therefore, the obtained triangle ABC is a right-angled triangle
