Draw a triangle ABC in which BC = 8 cm, ZB = 50° and ZA = 50°. Also bisect ZA and ZC.
Answers
Answer:
First draw a line segment BC=8 cm.
Then, draw 50° at B and extend the ray.(Now if A=50 and B is also 50°, then C=80°.by Angle Sum Property of a Triangle.)
Now draw 100° at C and extend it
The point where B and C meet is A.And finally bisect angle A and C.(A will be 25° & C will be 40°).
Hence ABC is required Triangle
Given;
BC=8BC=8 cm , \angle B=50∠B=50 degree and \angle A=50∠A=50
We know for a \bigtriangleup ABC△ABC ,
\angle A+\angle B+\angle C=180∠A+∠B+∠C=180
⇒\angle C=180-\angle A-\angle B∠C=180−∠A−∠B
⇒\angle C=180-50-50∠C=180−50−50 (By plug the values)
⇒\angle C=80∠C=80
Step 1=Draw line BCBC (8 cm)
Step 2=From point BB draw 5050 degree line BXBX
Step 3=From point CC draw 8080 degree line CYCY which cuts BXBX at AA
Step 4=And also bisect the angle AA and CC as soon in figure.
Now ABC is required triangle.
