What is a midsegment of a triangle?

Back

A midsegment of a triangle is a segment that connects the midpoints of two sides of the triangle. It is parallel to the third side and its length is half the length of that side.

How do you calculate the area of a triangle?

Back

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

Front

What is the product of the polynomials (2x - 1)(3x + 4)?

Back

6x^2 + 5x - 4.

Front

What is rotation in geometry?

Back

Rotation is a transformation that turns a shape around a fixed point, known as the center of rotation, by a certain angle.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines it intersects. They are equal when the lines are parallel.

Front

What is the formula for the area of a triangle with base (x + 2) and height (2x - 1)?

Back

Area = (1/2) * (x + 2) * (2x - 1) = x^2 + (3/2)x - 1.

Front

What is the relationship between angle 5 and angle 3 if they are alternate interior angles?

Back

If angle 5 and angle 3 are alternate interior angles, they are equal when the lines are parallel.

Front

What is the definition of a polynomial?

Back

A polynomial is a mathematical expression that consists of variables, coefficients, and non-negative integer exponents, combined using addition, subtraction, and multiplication.

Front

How do you find the length of a midsegment in a triangle?

Back

The length of a midsegment is equal to half the length of the third side of the triangle.

Front

What is the difference between reflection and rotation?

Back

Reflection flips a shape over a line, creating a mirror image, while rotation turns a shape around a point.
