Classifying Triangles Ang-Sides, Solving Tri (pg 52-67)

Front

What is a scalene triangle?

Back

A scalene triangle is a triangle in which all three sides are of different lengths.

Front

How do you classify a triangle by its sides?

Back

Triangles can be classified as equilateral (all sides equal), isosceles (two sides equal), or scalene (no sides equal).

Front

What is an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length.

Front

What is an equilateral triangle?

Back

An equilateral triangle is a triangle in which all three sides are equal in length and all three angles are equal.

Front

What is the definition of a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

What is the difference between acute and obtuse triangles?

Back

An acute triangle has all angles less than 90 degrees, while an obtuse triangle has one angle greater than 90 degrees.

Front

How do you classify a triangle by its angles?

Back

Triangles can be classified as acute (all angles < 90°), right (one angle = 90°), or obtuse (one angle > 90°).

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Front

If a triangle has sides of lengths 5, 5, and 8, how would you classify it?

Back

The triangle is classified as isosceles because it has two sides of equal length.

Front

What is the formula to find the area of a triangle?

Back

The area of a triangle can be found using the formula: Area = 1/2 * base * height.
