1. What are the formulas for finding angles in geometry?
Ans. The formulas for finding angles in geometry include the sum of interior angles in a polygon, the sum of exterior angles in a polygon, and the angle sum property of a triangle.
2. How do you calculate the sum of interior angles in a polygon?
Ans. The formula to calculate the sum of interior angles in a polygon is (n-2) * 180 degrees, where n represents the number of sides in the polygon.
3. What is the formula for finding the sum of exterior angles in a polygon?
Ans. The formula for finding the sum of exterior angles in a polygon is always 360 degrees, regardless of the number of sides in the polygon.
4. How can the angle sum property of a triangle be used to find missing angles?
Ans. The angle sum property of a triangle states that the sum of the three interior angles of a triangle is always 180 degrees. By using this property, you can find missing angles in a triangle by subtracting the known angles from 180 degrees.
5. Can these angle formulas be applied to any type of polygon?
Ans. Yes, the formulas for finding angles in geometry can be applied to any type of polygon, as long as you know the number of sides in the polygon.
