Quarterly #3 Review

Front

What is the angle of elevation?

Back

The angle of elevation is the angle formed by the horizontal line and the line of sight to an object above the horizontal level.

Front

How do you calculate the height of an object using the angle of elevation?

Back

Use the formula: height = distance * tan(angle of elevation).

Front

What are the coordinates of a point that divides a line segment in a given ratio?

Back

Use the section formula: P(x,y) = ((mx2 + nx1)/(m+n), (my2 + ny1)/(m+n)) where m:n is the ratio.

Front

What does it mean for two triangles to be similar?

Back

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

Front

What are the properties of a rhombus?

Back

A rhombus has all sides equal, opposite angles equal, and its diagonals bisect each other at right angles.

Front

What is the relationship between the diagonals of a rectangle?

Back

The diagonals of a rectangle are equal in length and bisect each other.

Front

How do you find the length of the diameter of a circle given its center and a point on the circle?

Back

Use the distance formula: diameter = 2 * √((x2 - x1)² + (y2 - y1)²).

Front

What is the distance formula in a coordinate plane?

Back

The distance between two points (x1, y1) and (x2, y2) is given by: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the definition of a square?

Back

A square is a quadrilateral with all sides equal and all angles equal to 90 degrees.

Front

What is a rectangle?

Back

A rectangle is a quadrilateral with opposite sides equal and all angles equal to 90 degrees.
