What is the Triangle Inequality Theorem?

Back

The Triangle Inequality Theorem states that for any triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

Front

Can segments of lengths 3, 5, and 7 form a triangle?

Back

Yes, these segments can form a triangle according to the Triangle Inequality Theorem.

How do you determine the value of x in a geometric diagram?

Back

To determine the value of x, use the properties of angles, such as the sum of angles in a triangle or the relationships between angles in parallel lines.

Front

What is an angle bisector?

Back

An angle bisector is a line or ray that divides an angle into two equal parts.

Front

In a parallelogram, what is true about opposite angles?

Back

In a parallelogram, opposite angles are equal.

Front

If m∠A in a parallelogram is 78.2°, what is m∠C?

Back

m∠C is also 78.2° because opposite angles in a parallelogram are equal.

Front

What is the formula for finding the number of diagonals in a polygon?

Back

The formula for finding the number of diagonals in a polygon is n(n-3)/2, where n is the number of sides.

Front

How many diagonals can be drawn from a single vertex of a polygon with n sides?

Back

The number of diagonals that can be drawn from a single vertex of a polygon is equal to n - 3.

Front

What is a conjecture in mathematics?

Back

A conjecture is a statement that is believed to be true based on observations but has not yet been proven.

Front

What is the relationship between the number of sides and the number of diagonals in a polygon?

Back

The number of diagonals drawn from a single vertex of a polygon is equal to the number of sides of the polygon minus 3.
