Question

draw an obtuse -angled triangle and a right angled triangle find the point of ​

Answer 1

Answer:

120,60

Step-by-step explanation:

obtuse triangle

Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees. Since, ∠A is 120 degrees, the sum of ∠B and ∠C will be less than 90° degrees.

In the above triangle, ∠A + ∠B + ∠C = 180° (because of the Angle Sum Property)

Since ∠A = 120°, therefore, ∠B + ∠C= 60°.

Hence, if one angle of the triangle is obtuse, then the other two angles with always be acute.
