Question

Practical of Geometry :
1) Contruct Triangle ABC such that angle A = 45°, angle B = 55° and AC = 4.5cm

with construction!​

Answer 1

$\red{A}\pink{N}\orange{S}\green{W}\blue{E}\gray{R}$

Steps of Construction:

(i) Draw a line segment which is sufficiently long using ruler.

(ii) Locate points A and B on it such that AB=4.5cm.

(iii) At A, construct a line segment AE, sufficiently large, such that ∠BAC at 60°, use protractor to measure 60°

(iv) With A as centre and radius 5.5cm, draw the line cutting AE at C, join BC.

Then ABC is the required triangle.
