Question

1) Construct Triangle ABC In which BC=4cm B=90 AB+AC= 8 cm
Draw diagram (compulsory) write steps too
2)Construct triangle ABC Where BC=6cm b=45 Ab-Ac=2
No need of steps

Answer 1

Answer:

Steps of construction:

(1) Draw a line segment XY.

(2) Locate B, C on XY such that BC=4cm

(3)Construct a line segment BD, sufficiently large, such that ∠B=90°

(4)With C as centre and radius 5cm draw an arc, cutting BD at A; join AC.

Then, ABC is the required triangle.

Step-by-step explanation:

The correct option is B From ray BY, cut-off line segement BD = 2.5 cm

Step 3: From ray BY, cut-off line segement BD = 2.5 cm. Join CD

Step 4: Draw perpendicular bisector of CD intersecting BY at A.

Step 5: Join AC,

Δ

A

B

C

is the required triangle.
