Review for CO

1.   What was the focus of our last discussion?

• Pythagorean Theorem

• Six Trigonometric Ratios

• Quadratic Formula

• Similarity Theorem

When do we use the trigonometric ratios?

• We use trigonometric ratios in right triangle.

• We use trigonometric ratios in rectangle.

• We use trigonometric ratios in right trapezoid.

• We use trigonometric ratios in right angles only.

Among the six trigonometric ratios, what is common that we use in

solving right triangle?

• Sine, Cosecant and Tangent

• Sine, Cosine, and Cotangent

• Secant, Cosecant, Cotangent

• Sine, Cosine, and Tangent

When do we use sine?

• When two sides of a triangle are given

• When the opposite side and the hypothenuse are given

• When the opposite side and the adjacent side are given

• When the adjacent side and the hypothenuse are given

When do we use cosine?

• When the adjacent side and hypothenuse are given

• When the adjacent side and opposite side are given

• When two sides of a triangle are given

• All of the above

When do we use tangent?

• When the adjacent side and hypothenuse are given

• When both legs of the triangle are given.

• When the opposite side and the hypothenuse are given

• None of the above
