Question

20 points help!!!Find ∠C and hence classify each triangle according to:

a. the number of equal sides it has, and
b. the type of angles it has, e.g. equilateral triangle & acute-angled
triangle.
Given Angles ∠C Number of equal
sides

Types of Triangle .∠A = 70
∠B = 40

Answer 1

the same type of question is there

Explanation:

triangle is scalene if all of its three sides are different (in which case, the three angles are also different). If two of its sides are equal, a triangle is called isosceles. A triangle with all three equal sides is called equilateral

Answer 2

a) 2

b) isosceles and acute-angled triangle

Explanation:

∠A = 70

∠B = 40

∠C = 180 - 70 - 40 = 70

Two equal angles so 2 equal sides

It's an isosceles triangle

Since all angles are acute, it's also an acute angled triangle
