Question

5. Which of the triangles whose sides are given below can be constructed?
(a) 2 cm, 5 cm, 8 cm

(b) 10 cm, 5 cm, 7cm (c) 13 cm, 5 cm, 7cm







​

Answer 1

Answer:

10,5,7

Explanation:

because 10+5=15>7

Answer 2

Answer:

so in this sum all the 3 sides of the triangle is given

STEP 1: Take any side of the triangle and draw the base (suppose from part a the base is 8cm so draw an horizontal line of 8 cm which is the base of the triangle)

STEP 2: Take a compass with the radius of the second side suppose 5cm. with one end of the 8cm line as the center draw an arc.

STEP 3: Repeat step 2 with the 3rd side I.e 2 cm and with the other end of the 8 cm line draw an arc.

STEP 3 : The point at with both the arcs meet is the 3rd vertex of the triangle and now join the sides of the triangle.

These steps are to be followed for part b and c
