Identifying Triangles

In a triangle, how many total degrees are there?

• 100%

• 180 degrees

• it varies

• 360 degrees

A triangle has angle measurements of 26°, 59°, and 95°. What kind of triangle is it?

• acute triangle

• right triangle

• obtuse triangle

• none of the above

Find the measure of the missing angle.

• 90^o

• 10⁰

• 130^o

• 50^o

Identify the triangle by its sides and angles

• Equilateral

• Obtuse Equilateral

• Acute Equilateral

• Acute Isosceles

Identify the triangle by its sides and angles

• Right Isosceles

• Right Scalene

• Obtuse Isosceles

• Obtuse Scalene

Identify the triangle by its sides and angles

• Obtuse

• Acute Isosceles

• Obtuse Scalene

• Obtuse Isosceles

Identify the triangle by its sides and angles

• Right Isosceles

• Right Scalene

• Right Equilateral

All acute triangle are Equilateral

• True

• False

Use the angles to classify the triangles

all angles less than 90° - acute triangle

1 angle is equal to 90° - right triangle

1 angle is greater than 90° - obtuse triangle

Use the sides to identify the triangle

0 sides the same - scalene triangle

2 sides the same - isosceles triangle

3 sides the same - equilateral triangle
