4.1-4.2 Congruent Triangles Practice

Front

Classify the triangle by its sides: What is a Scalene triangle?

Back

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

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.

Front

If ∆EHG≅∆KFC, what can we say about the corresponding sides?

Back

The corresponding sides of congruent triangles are equal in length.

Front

Classify the triangle by its angles: What is an Acute triangle?

Back

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

Front

What is the definition of an Isosceles triangle?

Back

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

Front

If AB≅XY, what does this indicate about the triangles?

Back

This indicates that the sides AB and XY are equal in length, which is a property of congruent triangles.

Front

Solve for x: If x + 2 = 6, what is x?

Back

x = 4.

Front

What is the definition of a Right triangle?

Back

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

Front

If ∆ABC≅∆XYZ, what can we conclude about the angles?

Back

The corresponding angles of the triangles are equal.

Front

What is a Scalene triangle?

Back

A scalene triangle is a triangle with all sides of different lengths.
