Classifying Triangles and finding Angles

Front

What is an Isosceles triangle?

Back

A triangle with at least two sides of equal length.

Front

What is an Equilateral triangle?

Back

A triangle where all three sides are of equal length.

Front

What is a Scalene triangle?

Back

A triangle with all sides of different lengths.

Front

What defines an Acute triangle?

Back

A triangle where all three angles are less than 90 degrees.

Front

What defines an Obtuse triangle?

Back

A triangle that has one angle greater than 90 degrees.

Front

How do you classify triangles based on angles?

Back

Triangles can be classified as Acute, Right, or Obtuse based on their angles.

Front

How do you classify triangles based on sides?

Back

Triangles can be classified as Equilateral, Isosceles, or Scalene based on their sides.

Front

What is the sum of the angles in any triangle?

Back

The sum of the angles in any triangle is always 180 degrees.

Front

If two angles of a triangle are 54 degrees and 27 degrees, what is the third angle?

Back

The third angle is 99 degrees (180 - 54 - 27).

Front

What is the measure of an angle in an Isosceles triangle if the other two angles are equal?

Back

If the other two angles are equal, each angle can be calculated as (180 - x)/2, where x is the measure of the unequal angle.
