Triangle Classifications

Triangle Classifications Sort the following terms by triangle side andangle classifications. Angles Acute Obtuse Right Sides Scalene Isosceles Equilateral Classify each triangle based on the length of the sides. Isosceles Triangle A triangle that has two equal sides. Scalene Triangle A triangle that has no equal sides. Equilateral Triangle A triangle that has three equal sides. Classify each type of triangle based on the types of angles. Right Triangle A triangle with one right angle and two acute angles. Obtuse Triangle A triangle with one obtuse angle and two acute angles. Acute Triangle A triangle with three acute angles. What type of triangle is this? Acute Obtuse Right What type of triangle is this? Right Triangle Scalene Triangle Equilateral Triangle Triangle Inequality Theorem Watch the video before moving on. Determine whether the side lengths will make a triangle. Triangle 5, 8, 6 cm 2.5, 4.7, 6.8 yd NOPE! 12, 4, 8 in 2, 5, 9 ft Fill in the blanks using triangle vocabulary terms. A triangle is a polygon with 3 sides.An isosceles triangle has 2 equal sides.A scalene triangle has no equal sides.An equilateral triangle has 3 equal sides.An obtuse triangle has one angle that is greater than 90 degrees.A right triangle has one angle that is 90 degrees.An acute triangle has no angles that are greater than 90 degrees.Congruent triangles are triangles that have the same angles and sides.Supplementary angles form a line and add to 180 degrees.The Triangle Sum Theorem states that the interior angles of a triangle add to 180 degrees.The Triangle Inequality Theorem states that the sum of any two sides of a triangle must be greater than the third side. We learned that triangle's interior angles add to 180 degrees because the 3 angles, when put next to each other, form a . . . Circle Line Triangle Square
