Not too sure of the question and answer needed but if it is a right angle triangle with an hypotenuse of 25 units then to comply with Pythagoras; theorem it sides must be 15 units and 20 units.

How do you determine if a triangle is a right triangle?

For a right angled triangle, sum of squares of two sides of a triangle equals square of the third side. For example - In triangle ABC, AB2 + BC2 = AC2


What type of triangle is angle ABC?

ABC angle is an angle,not a triangle!


What are the classification of triangle according to sides and angles?

Classification of Triangles According to anglesIf one angle of a triangle is a right angle (90°), then it is called a Right triangle. Note that the other two angles are acute.If all the angles of a triangle are acute (less than 90°), then it is called an acute angled triangle.If one angle of a triangle is obtuse (greater than 90°), then it is called an obtuse triangle. Note that the other two angles are acute.According to sides:If any two sides of a triangle are equal, then it is called an Isosceles Triangle. In ABC, AB = AC ABC is isosceles.If all the three sides of a triangle are equal, then it is an Equilateral Triangle. In ABC, AB = BC = CA ABC is equilateral.If no two sides of a triangle are equal, then it is called a Scalene Triangle. In ABC, AB BC CA. ABC is scalene.


Side ac equals 12 side bc equals 16 and side ab equals 20 is triangle abc a right triangle?

yes


How do you find angles of a triangle?

I cannot answer this without knowing any more information. Finding the proper dimensions of a triangle without knowing the kind of triangle cannot really be done. Because it may be an isosceles triangle (every angle is equal) or it could be a 30-60-90 triangle etc.

What is the length of ad if the hypotenuse of the right angles are ab 20 bc 15 and abd and abc?

If the sides of the triangle are 20 and 15 then by using Pythagoras' theorem the length of the hypotenuse works out as 25 units of measurement.


How can you find the base of a triangle if you know the height and hypotenuse?

Let consider the right triangle ABC with hypotenuse AB and heigth AC then base is BC Pythagorean theorem states that AB2=AC2+BC2 so BC2=AB2-AC2 then BC=sqrt(AB2-AC2)


Triangle abc is a right triangle if side ac equals 5 and side bc equals 6 what is the measure of side ab?

If CB is the hypotenuse, then AB measures, √ (62 - 52) = √ 11 = 3.3166 (4dp) If AB is the hypotenuse then it measures, √ (62 + 52) = √ 61 = 7.8102 (4dp)


Triangle ABC is a right triangle. If side AC is 7 units and side BC is 10 units what is the measure of side AB?

By using Pythagoras' theorem for a right angle triangle if side AB is the hypotenuse it is the square root of 149 which is about 12.207 rounded to three decimal places


How do you calculate hypoteneous of a right angled triangle?

The hypotenuse is the longest side of the right triangle. To calculate the hypotenuse of a right triangle, you would square the sides, add them up, and find the square root of the sum. When you find the square root of the sum, that will be the hypotenuse of your right triangle. For instance, let's say you are given a triangle. We'll call it Triangle ABC. In the triangle, you have three sides, Side A, Side B, and Side C. Sides A and B will represent the two known legs, also the shortest legs. Side C will represent the hypotenuse, the side we're trying to find. We know that Side A is 5km and that Side B is 12km. Now we just have to calculate the hypotenuse of the right triangle. To do that you would square both sides and add them, first. Like this: (5 x 5) + (12 x 12) which is the same as saying 25 + 144. Now you find the sum, which is 169. Now, there is one last step, finding the square root of the sum. Our square root would be 13, because we know that 13 x 13=169. So now you have found the missing side, the hypotenuse of the right triangle (Side C) which is 13km. And that's how you find the hypotenuse of a right triangle. Hope I could help!


What is the length of the hypotenuse of the rigth triangle ABC in if AC 6 and AD 5?

Assuming you mean side AB is 5: If angle B is the right angle, side AC is the hypotenuse and is of length 6. If angle A is the right angle, side BC is the hypotenuse and is of length sqrt(52 + 62) ~= 7.81 Angle C cannot be the right angle as then side AB would be the hypotenuse but the hypotenuse is the longest side and side AB is shorter than AC.


In this triangle side AC 2 side BC 3 and side AB 4. Is triangle ABC a right triangle?

In right triangle ABC, angle C is a right angle, AB = 13and BC = 5 What is the length of AC? Draw the triangle to help visualize the problem.


Right triangle ABC has two legs of equal length. How long is a leg if the hypotenuse has a length of 19?

Each leg is the square root of 180.5 which is about 13.435 rounded to 3 decimal places
