sides and angles

Question 1

Define scalene sides:

Answer 1

Scalene sides are when the sides are different/no sides are congruent

Question 2

Define isosceles sides:

Answer 2

Isosceles sides are when there are two or more congruent sides

Question 3

How do you classify triangles with acute angles?

Answer 3

Angles less than 90 degrees

Question 4

How do you classify triangles with right angles?

Answer 4

Angles that are exactly 90 degrees/one right angle

Question 5

What are equilateral sides?

Answer 5

Equilateral sides are when they’re equal on each side/all sides are congruent

Question 6

What are equiangular angles?

Answer 6

Equiangular angles are when all angles are the same/all congruent angles

Question 7

How do you classify triangles with obtuse angles?

Answer 7

One obtuse angle

Question 8

Describe the anatomy of an isosceles triangle:

Answer 8

• The vertex will be on the very tip of the triangle
• There is one leg on each side (congruent sides)
• The base is located on the bottom of the triangle (and base angles are located in the corners of the base)

Question 9

What happens when you bisect the vertex angle of an isosceles triangle?

Answer 9

The triangle bisector is perpendicular to the base and it’s midpoint

Question 10

True or false; base angles of an isosceles triangle are congruent?

Answer 10

True because when you have an isosceles triangle, there are at least two or more congruent sides
