If the base of an isosceles triangle is 74 what is the measure of the vertex angle?

You can't calculate any angle if all you know is one side of the triangle.

How do you know if a triangle is a right triangle using the pythagorean therom?

We know that a right triangle is a triangle having a right angle, where the side opposite the right angle is the hypotenuse, and the perpendicular sides are the legs of the right triangle. The Pythagorean theorem gives the relationship between the lengths of the sides of a right triangles. In the case where you know only the measure lengths of the sides of a triangle, you need to test these measures. If one of the sides of the triangle has a square measure equal to the sum of the square measures of two other sides, then this side is called the hypotenuse and opposite to this side is a 90 degree angle, which is a right angle. So, you can say that this triangle is a right triangle. Pythagorean triple are very helpful to determine a right triangle, such as: (3, 4, 5), (5,12,13), (8, 15, 17), (7, 24, 25), and (20, 21, 29).


How do you find a scale factor of a triangle?

To find the scale factor of two triangles, look first for one pair of corresponding sides--one side from the smaller triangle and the corresponding side from the larger triangle. Divide the larger side length by the smaller side length, and that quotient is your scale factor.

How do you calculate the perimeter of a triangle?

-- Measure or calculate the length of one side. -- Measure or calculate the length of another side. -- Measure or calculate the length of the only remaining side. -- Add the three numbers. The sum is the perimeter of the triangle.


What is the value of X in a right triangle if one side is 14 and the hypotenuse is 28?

It depends on whether X is the missing side, one of the angles or some other measure of the triangle.

How to calculate the sides of a triangle given the degree of an angle and one side?

The measure of only one angle and one side is not sufficient to calculate the lengths of the sides of a triangle. If you have one more angle or one more side you can use the sine rule.


What is the measure of the sides of an isosceles triangle if one side equals 12.1?

If one side of an isoceles triangle has a measure of 12.1, then either... 1. One of the other sides is also 12.1. ...or... 2. The other two side as equal to each other but not equal to the known side. In both cases, the unknown side(s) are unknown, because the angles are not stated.
