Angle of Depression- An angle made at where the horizontal line and the line of sight to a point above the line.
Anlge of Elevation- An angle made at where the horizontal line and the line of sight to a point below the line.
Line of Sight- The diagonal line between the angle of depression and elevation's horizontal line.

Line of Sight- The diagonal line between the angle of depression and elevation's horizontal line.
Angle-Angle Similarity Postulate(AA~) - States that if two angles of two triangles are congruent, they'd be similar.
Side-Side-Side Similarity Postulate(SSS~) - States that if three sides of two triangles(must correspond) are proportional to each other, they'd be similar.
Side-Angle-Side Similarity Postulate(SAS~) - States that if two sides pf the two triangles are proportional and the included angles of two triangles are congruent, they'd be similar.

Dilation- The size of a figure will change but not the shape; is a form of transformation.
Scale Factor- How much the figure's size is enlarged or reduced.
Scale Factor- How much the figure's size is enlarged or reduced.
Geometric Mean- The positive square root of two positive numbers.
Trigonometric Ratio- The ratio of two sides of a right triangle.
Sine(sin)- Angle of the ratio of the length of the leg opposite the angle to the length of the hypotenuse.
Cosine(cos)- Angle of the ratio of the length of the leg adjacent to the angle to the length of the hypotenuse.
Tangent(tan)- Angle of the ratio of the length of the leg opposite the angle to the length of the leg adjacent to the angle.
Trigonometric Ratio- The ratio of two sides of a right triangle.
Sine(sin)- Angle of the ratio of the length of the leg opposite the angle to the length of the hypotenuse.
Cosine(cos)- Angle of the ratio of the length of the leg adjacent to the angle to the length of the hypotenuse.
Tangent(tan)- Angle of the ratio of the length of the leg opposite the angle to the length of the leg adjacent to the angle.
Triangle Proportionality Theorem- If a line parallel to a side of a triangle intersects the other two sides, then it divides
