Answer 1

ΔABC is constructed in which AB = 4.5 cm, ∠A = 30°, and AC =2 cm

Step-by-step explanation:

Please post Question separately one by one

answering

Construct a triangle ABC in which AB = 4.5 cm, ZA = 30°, and AC =2

Step 1 :  Draw a line segment AB = 4.5  cm

Step 2 : Taking suitable width of compass & taking A as center , draw an arc intersecting AB at M

Step 3 : keeping compass width Same taking M as center , draw arc intersecting earlier drawn arc at N

Step 4 : Reducing compass width slightly & taking M as center draw an arc

Step 5 : keeping compass width same as in step 4 and taking N as center draw arc ,intersecting arc drawn in step 4 at O

Step 6 : Draw a ray starting from A and passing through O

Step 7 : Take a length of  2 cm from A on Ray drawn in step 6 and mark other end as C

Step 8 : join BC

ΔABC is constructed in which AB = 4.5 cm, ∠A = 30°, and AC =2 cm
