The length of the two equal sides is not enough information to uniquely determine the length of the base.
With sides of 10 cm, you can draw a triangle with anybase that's longer than zero and shorter than 20 cm.
The height can be anything taller than zero and shorter than 10 cm.
You look at the lengths of the sided of the triangle. If the two lengths are same, the triangle is an isosceles triangle. If all the lengths are same, the triangle is an equilateral triangle. If none of the lengths are same, the triangle is a scalene triangle.
The triangle with angles measuring 50 degrees, 65 degrees, and 65 degrees is an isosceles triangle. In an isosceles triangle, two of the three angles are equal, making it a special type of triangle. In this case, the two angles measuring 65 degrees are equal, indicating that the two sides opposite these angles are also equal in length.
Only a right triangle has a hypotenuse. An isosceles triangle can be a right triangle but it doesn't have to be. If it's not, then it doesn't have a hypotenuse.
The perimeter of a shape is the sum of the lengths of all its sides. In this case, the shape is a rectangle with sides measuring 7cm and 10cm. To find the perimeter, you add up all the sides: 7cm + 7cm + 10cm + 10cm = 34cm. Therefore, the perimeter of this shape is 34cm.
To find the area of a triangle, you use the formula: Area = 1/2 * base * height. Plugging in the values, we get Area = 1/2 * 10cm * 15cm = 75 square cm. Therefore, the area of the triangle with a base of 10cm and a height of 15cm is 75 square cm.
An isosceles triangle has 3 sides 2 of which are equal in length
isoselceles triangel is tow sides areequal
i can
The answer depends on what information you have but, basically, you need to add together the lengths of the three sides of the triangle.
It is a right angle triangle and its largest angle is 90 degrees
You look at the lengths of the sided of the triangle. If the two lengths are same, the triangle is an isosceles triangle. If all the lengths are same, the triangle is an equilateral triangle. If none of the lengths are same, the triangle is a scalene triangle.
An isosceles triangle is a triangle with two equal sides. To find the perimeter of the triangle, you simply need to add together the lengths of the base and the two sides. So: 3.9 + 4.6 +4.6 = 13.1 inches.
Assuming that neither of the sides of equal length is the base, Perimeter = Base + 2*Slanted sides.
By using Pythagoras' theorem.
That's because it is possible to find two sides that have the same length.
It depends on what information you have: one side and an angle, two different sides.
Make it a right triangle where one side of the right triangle is half the length of the non-identical side of the isosceles, the hypotenuse of the right triangle is the length of one of the identical sides of the isosceles triangle, then use the Pythagorean theorem. a^2+b^2=c^2. Where "a" is the length of one of the identical sides, and "c" is the length of half the non-identical sides. Solve for "b" and that is your height.
