WebMar 20, 2012 · You will need the fact that two triangles are congruent if and only if they have the same side lengths. There is general theory, but just try to make a complete list, by being very systematic. The longest side is 11. There is no other side of length 11, since the triangle is scalene, and in particular not isosceles. WebSide lengths: 6, 3, 4. Given the three given lengths of the sides determine if the triangle is scalene, isosceles or equilateral and if it is acute, right or obtuse. Side lengths: 5, 3, 4. Two sides of a triangle measure 4 inches and 7 inches. dwayne p mitchell

WebExample 2: Calculate the length of the altitude of a scalene triangle whose sides are 7 units, 8 units, and 9 units respectively. Solution: The perimeter of a triangle is the sum of all the sides = 7 + 8 + 9 = 24 units. Semi-perimeter (s) = 24/2 =12 units. Let us name the sides of the scalene triangle to be 'a', 'b', and 'c' respectively. WebHow many sides does a regular polygon have if each interior angle measures 178°?
