Front

What is a Right Scalene triangle?

Back

A Right Scalene triangle is a triangle with one right angle and all sides of different lengths.

Front

What does the SAS postulate state?

Back

The SAS (Side-Angle-Side) postulate states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the two triangles are congruent.

Front

What is an Obtuse Isosceles triangle?

Back

An Obtuse Isosceles triangle is a triangle with one obtuse angle and two sides of equal length.

Front

How do you find the slope of a line from its equation?

Back

The slope of a line in the form y = mx + b is given by the coefficient m. For example, in y = -1/2x - 2, the slope is -1/2.

Front

What is a Line in geometry?

Back

A Line is a straight one-dimensional figure that has no thickness and extends infinitely in both directions.

Front

What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices.

Front

What are the types of triangles based on angles?

Back

Triangles can be classified as Acute (all angles < 90°), Right (one angle = 90°), or Obtuse (one angle > 90°).

Front

What is the difference between a Line Segment and a Ray?

Back

A Line Segment has two endpoints, while a Ray has one endpoint and extends infinitely in one direction.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

What is the SSS postulate?

Back

The SSS (Side-Side-Side) postulate states that if three sides of one triangle are equal to three sides of another triangle, then the two triangles are congruent.
