Front

What are the types of triangles based on their sides?

Back

The types of triangles based on their sides are: equilateral (all sides equal), isosceles (two sides equal), and scalene (no sides equal).

Front

What are the types of triangles based on their angles?

Back

The types of triangles based on their angles are: acute (all angles less than 90°), right (one angle equal to 90°), and obtuse (one angle greater than 90°).

How do you plot a point in a Cartesian coordinate system?

Back

To plot a point in a Cartesian coordinate system, move horizontally to the x-coordinate and vertically to the y-coordinate.

Front

What is the coordinate of the origin in a Cartesian plane?

Back

The coordinate of the origin in a Cartesian plane is (0, 0).

Front

What does the x-coordinate represent in a point (x, y)?

Back

The x-coordinate represents the horizontal position of the point on the Cartesian plane.

Front

What does the y-coordinate represent in a point (x, y)?

Back

The y-coordinate represents the vertical position of the point on the Cartesian plane.

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the area formula for a triangle?

Back

The area of a triangle is given by the formula: Area = 1/2 * base * height.
