Across
- 1. a triangle with at least two congruent sides
- 3. a line from the center of a regular polygon at right angles to any of its sides
- 4. inverse of sine
- 6. is A ratio of the lengths of two sides in a right triangle
- 8. the angle between the line of sight and the horizontal when an observer looks downward
