Question

5. (a) If each angle of a triangle is less than the sum of the other two, show that the triangle is acute
angled.
[Hint. Let angleA < angleB + angleC then 2 angleA < angleA + angleB + angleC => 2 angleA < 180° > angleA < 90°.
Similarly, angleB < 90° and angleC < 90°]

(b) One angle of a triangle is greater than the sum of the other two. What can you say about the measure of this angle? What type of a triangle is this?
