What is the center of a circle in coordinate geometry?

Back

The center of a circle is a point in the plane from which all points on the circle are equidistant. It is represented as (x, y) in coordinate geometry.

How do you find the center of a circle given its equation?

Back

For a circle in the standard form (x - h)² + (y - k)² = r², the center is (h, k).

What is a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

What does it mean for two shapes to be similar?

Back

Two shapes are similar if they have the same shape but not necessarily the same size; their corresponding angles are equal and their corresponding sides are in proportion.

How do you determine corresponding points in similar figures?

Back

Corresponding points in similar figures are matched based on the order of the vertices and the angles of the shapes.

What is the formula for the area of a trapezoid?

Back

The area A of a trapezoid is given by the formula A = (1/2) * (b1 + b2) * h, where b1 and b2 are the lengths of the two parallel sides and h is the height.

How do you identify the coordinates of a point in a Cartesian plane?

Back

The coordinates of a point are given as (x, y), where x is the horizontal distance from the origin and y is the vertical distance from the origin.
