Take home Flashcard Chapter 2/part 2

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a theorem stating that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the relationship between parallel lines and triangles?

Back

If a line is parallel to two sides of a triangle and intersects the third side, it divides the two sides proportionally.

Front

What does it mean for polygons to be similar?

Back

Polygons are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a theorem stating 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 triangles are congruent.

Front

If two polygons are not similar, what does that imply?

Back

It implies that their corresponding angles are not equal or their corresponding sides are not in proportion.

Front

What is the measurement of angle X if pentagon JKLMN is similar to pentagon VWXYZ and angle X corresponds to an angle of 120 degrees in JKLMN?

Back

Angle X measures 120 degrees.

Front

What is the significance of the AA criterion in triangle similarity?

Back

The AA criterion states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is the definition of a triangle?

Back

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

Front

What is the formula for the sum of interior angles in a polygon?

Back

The sum of the interior angles of a polygon with n sides is (n-2) × 180 degrees.

Front

What is the difference between congruent and similar figures?

Back

Congruent figures are identical in shape and size, while similar figures have the same shape but may differ in size.
