Subsequent worksheets have the base angle rotated slightly which requires more spatial thinking, and the final set of worksheets has angles that are near right angles and may require a protractor to determine if their are acute or obtuse. Conversely, the longer the side the greater the measure of the opposing angle. Notice that ∠PON and ∠MON must be acute angles since their sum is equal to the measure of a right angle (90°). sinA/a = sinB/b = sinC/c. One of the sides of this square coincides with a part of the longest side of the triangle. This activity involves three Halloween riddles that are solved by completing 16 equations. Celebrate Halloween while practicing multi-step equations. Some real-life examples of acute angles are: If we slice a pizza into 5 or more slices, each slice of pizza will make an acute angle. Math, Algebra, Other, Worksheets, Celebrate HALLOWEEN by solving two-step equations and coloring! Oblique triangles are broken into two types: acute triangles and obtuse triangles. Acute triangles can be isosceles, equilateral, or scalene. An acute triangle has three inscribed squares. An equilateral triangle has three sides of equal length and three equal angles of 60°. The worksheets start out with the base leg of the angle always laying horizontal, which is the easiest way to visualize whether the angle is acute or obtuse. For example, in an equilateral triangle, all three angles measure 60˚, making it an acute triangle. An equilateral triangle has three sides of equal length and three equal angles of 60°.

The worksheets start out with the base leg of the angle always laying horizontal, which is the easiest way to visualize whether the angle is acute or obtuse. If we plug in the expressions for the angle measures we get. Each slice of the pizza makes an acute angle. The 3 angles formed with vertices A,B, and C of the tent below have equal measure.
