Question 1.

Did you spot any other type of triangle? Class 7

Solution:

Yes.

Question 2.

What are the other types of triangles based on angle measures? Class 7

Solution:

Acute angled triangles, right triangles, obtuse angled triangles.

Question 3.

What could an acute-angled triangle be? Can we define it as a triangle with one acute angle? Why not? Class 7

Solution:

All angles are acute. No. Because with one acute angle, the other two angles, can either be right angles or obtuse angles. In that case, sum of the three angles shall be greater than 180°, which is impossible. (Example 30°, 90°, 110°. Their sum = 230° > 180°, etc.)
