Front

What is a triangle classified by its sides and angles?

Back

A triangle can be classified by its sides as Equilateral, Isosceles, or Scalene, and by its angles as Acute, Right, or Obtuse.

Front

Define an Acute Triangle.

Back

An Acute Triangle is a triangle where all three angles are less than 90 degrees.

Front

Define a Right Triangle.

Back

A Right Triangle is a triangle that has one angle equal to 90 degrees.

Front

Define an Obtuse Triangle.

Back

An Obtuse Triangle is a triangle where one angle is greater than 90 degrees.

Front

What is an Equilateral Triangle?

Back

An Equilateral Triangle is a triangle where all three sides are equal in length and all three angles are equal, each measuring 60 degrees.

Front

What is an Isosceles Triangle?

Back

An Isosceles Triangle is a triangle that has at least two sides of equal length and the angles opposite those sides are equal.

Front

What is a Scalene Triangle?

Back

A Scalene Triangle is a triangle where all three sides are of different lengths and all three angles are different.

Front

How do you identify an Acute Isosceles Triangle?

Back

An Acute Isosceles Triangle has two equal sides and all angles are less than 90 degrees.

Front

How do you identify a Right Scalene Triangle?

Back

A Right Scalene Triangle has one angle equal to 90 degrees and all sides of different lengths.

Front

How do you identify an Obtuse Scalene Triangle?

Back

An Obtuse Scalene Triangle has one angle greater than 90 degrees and all sides of different lengths.
