Find the base of a triangle by solving the equation: area = 1/2 x b x h. You need to know the area and height to solve this equation.
Continue ReadingPut the area before the equals sign, and replace the letter h with the height. For example, if the area is 15 centimeters, and the height is 10 centimeters, the equation would look like this: 15 = 1/2 x b x 10.
Calculate 1/2 x h/1 to get h/2. For example, 1/2 x 10/1 equals 10/2, which equals 5. Now the equation looks like this: 15 = 5b.
To isolate b, divide the entire equation by the number on the same side of the equation as b. For example, 15 = 5b becomes 15/5 = 5b/5. Five divided by 5 equals 1, so b is now alone on one side of the equation, which now reads 15/5 = b.
Divide the numbers on the other side of the equation to solve for b. For example, 15 divided by 5 is 3, so 3 = b. The base of the triangle measures 3 centimeters.
A scalene triangle has no equal sides. There is no word for a triangle with three different angle sizes. The words describing angle sizes — right, obtuse and acute — reference the degrees of the angle, not their relationships to one another.
Full Answer >The orthocenter is defined as the point where the altitudes of a right triangle's three inner angles meet. It is also the vertex of the right angle.
Full Answer >The hypotenuse of a right triangle is calculated by finding the square root of the sum of the squares of the triangle's legs. It can be expressed using the formula c = √(a^{2} + b^{2}), where a and b represent the legs of the triangle and c indicates the hypotenuse.
Full Answer >A shape that has three unequal sides is a scalene triangle. A shape that has four unequal sides is a quadrilateral. A shape that has more than four unequal sides is an irregular polygon.
