Two statements are given: Statement I: In \(\triangle A B C, A B=6 \sqrt{3} \mathrm{~cm}, A C=12 \mathrm{~cm}\) and \(B C=6 \mathrm{~cm}\), then angle \(B=90^{\circ}\) Statement II: \(\triangle A B…
Question and options
Two statements are given:
Statement I: In and , then angle
Statement II: is isosceles with . If , Then angle
In the light of the given statements, choose the correct answer from the given options:
Statement I: In and , then angle
Statement II: is isosceles with . If , Then angle
In the light of the given statements, choose the correct answer from the given options:
- Both Statement I and Statement II are true
- Both Statement I and Statement II are false
- Statement I is true but Statement II is false
- Statement I is false but Statement II is true
Answer and explanation
Correct answer: A - Both Statement I and Statement II are true
I: AB^2 + BC^2 = 108 + 36 = 144 = AC^2, so angle B = 90 deg (true). II: AB^2 = 2AC^2 = AC^2 + BC^2, so angle C = 90 deg (true).
