Question

construct a triangle ABC with BC is equal to 7 cm angle b is equal to 60 degree and a b is equal to 6 cm and construct an another triangle whose sides are 3 by 4 times the corresponding sides of triangle ABC. And also write steps of construction.​

Answer 1

Answer:

HEY MATE !!!!!!!!

Step-by-step explanation:

STEPS OF CONSTRUCTION:

1. Draw a line segment BC =7cm.

2. At B draw ∠CBY = 60° and cut off BA =6 cm from it.

3. Join AC. Thus ∆ABC is a given Triangle.

4. Now from B draw a ray BX making an acute ∠CBX  on the side opposite to the vertex A.

5. Mark 4 points B1,B2,B3,B4 on BX such that BB1 = B1B2 = B2B3 = B3B4.

6.Join B4C and from B3 draw B3C’ || B4C intersecting BC at C’.

7. From point C’ draw C’A’ || CA intersecting AB at A’. Thus , ∆A’B’C’  is the required triangle whose sides are 3/4 of the corresponding sides of ∆ABC.

Answer 2

$\boxed{\huge{\red{Construction}}}$

_________________________

→ Draw a line segment BC of 7 cm. Taking B as centre draw of 6 cm . Name the point of intersection A . Join AC .

→ Draw a ray BX making an acute angle with BC on opposite vertex AB

→ Locate 4 points on BX of 1 cm each and name them $B_{1},B_{2},B_{3},B_{4}$on line segment BX .

→ Join $B_{4}C||B_{3}C`$

→Join A`C` || AC
