A pentagon is a closed figure with 5 sides and 5 angles. It CAN have right angles and parallel lines, depending on how you draw it! The home plate in baseball is an example of a pentagon with two right angles and one pair of parallel sides.
An equilateral triangle has three sides of equal length and three equal angles. An isosceles triangle has two sides of equal length and two equal angles. A scalene triangle has no sides of equal length and no equal angles. A right angle triangle has one angle that is 90 degrees.An obtuse triangle has one angle larger than 90 degrees. An acute triangle has angles that are all less than 90 degrees.The longest side of a right angle triangle is called the hypotenuse, it is always found opposite the right angle.Trigonometry is the study of the relationship between the angles of triangles and their sides. Triangle shapes are often used in construction because of their great strength.he longest side of a right angle triangle is called the hypotenuse, it is always found opposite the right angle.
