What triangle has the angles 40 50 and 90 degrees?
The angles given would form a right angle triangle
Can angles with 40 90 and 50 degrees be an equilateral triangle?
No because the angles given are applicable to a right angle triangle whereas an equilateral triangles has 3 interior angles each measuring 60 degrees.
What is a triangle that has no equal sides and no equal angles?
It is a scalene triangle although a right angle triangle could also fit the given description under certain circumstances.
If one angle of a triangle is 90 degrees then the other two add to 90 degrees what is the given and the proof?
180
Which shape fits the description below A three-sided figure with one acute angle one right angle and one obtuse angle.?
A three sided shape is a triangle but the given angles are incorrect because a triangle can't possibly have a right angle and an obtuse angle because its 3 interior angles must add up to 180 degrees.
What is the measure of the angle named x?
It depends on what your measuring and the measure of the other given angles. "X" is also known as the missing angle. ex. In triangle ABC, the measure of angle A is 40 and the measure of angle B is 80 find the missing angle. answer- Angle C would be 60 because a triangle's angles add up to 180 degrees.
The angles of a triangle that are not adjacent to a given exterior angle?
Remote interior angles
You are trying to work out missing angles about certain points of angles in a triangle?
to find missing angles you are dealing with complementry and suplementry angles. Suplementry angles add up to 180 degrees so you must subtract what given angle you have from 180 and you come up with youre missing angle. This rule also gos for complementry but the angles must add up to 90 degrees
What triangle has the angles 40 50 and 90 degrees?
The angles given would form a right angle triangle
How do you find the missing angle of a square with no given angles?
All the angles of a square are 90 degrees.
How do you find out the height of a triangle if only the 3 angles are given?
It is impossible to find a triangle if only angle measures are given (all similar triangles have the same angles).
How do you find the angle of triangle if their sum and difference is given?
In plane Euclidean geometry there are 3 angles in any triangle that add up to 180 degrees and if given 2 angles the sum of the 2 angles minus 180 will give the measure of the 3rd angle
Is it possible to work out the other angles of a triangle given only one angle?
YesAnother Answer:-Yes under certain conditions depending on what type of triangle it is and the measure of the angle givenBut normally two angles are needed to find the third angle in a triangle
How do you find a missing dimension for a right angle triangle?
In a right triangle, all the angle measurements together add up to be 180 degrees. And since it is a right triangle, one of the three angles is 90 degrees so if you are given one of the angles other than the right angle's measurements, you can find the angle measurements. Here's an example: There is a right triangle. One angle measures to be 45 degrees. What is the missing angle measure? Well we know that one angle must be 90 degrees and the other (as we were told) is 45 degrees. 90+45=135 and we know that a right triangle=180 degrees total and 180-135= 45. The missing angle is equal to 45 degrees! hope this makes sense and it helped.
How do you find a missing angle on a triangle?
You must use the formulas you know that describe the properties of triangles to relate the information you're given to the size of the unknown angle. Do you want to know the measurement / size of the angle. The internal angles of a triangle add up to 180 degrees. If you know two angles then add them together eg 60 + 30 = 90 now subtract 90 from 180, 180-90 = 90 So the missing angle is 90 degrees
How do you find a third angle?
I am guessing you mean you are given 2 of the 3 interior angles of a triangle and are asked for the 3rd. Well, it is a theorem that the 3 angles of a triangle add up to 180 degrees. So add the 2 given angles and subtract the sum from 180. to get the measure of the 3rd angle.
How do you find the measure of an angle in a triangle?
Add together the given angles, or the angles you already know or have been given measures for, and then subtract the added numbers from 180 and that is you answer.
