What does a obtuse triangle equal?
An obtuse triangle equals 180°, like all other triangles but it must have one angle that is greater than 90°.
How many obtuse isosceles triangles are there?
infinite amounts of isosceles triangles as any length can be any size, just in the same ratio to each other.
What is the fraction of 3 triangles?
The answer will depend on what the fraction relates to: their perimeter, their area, some other aspect.
How are an obtuse and right triangle the same?
Obtuse triangles and right triangles certainly are not the same, but there are three features both have in common: Both have 3 sides Both have 3 interior angles Both have a single side which is longer than either of the other two, but shorter than the sum of the other two.
How do you make a triangle with 2 triangles and 1 rectangle?
If the 2 triangles are right triangles, which are congruent to slicing the rectangle on the diagonal, then arrange one on top of the rectangle, and the other to the side, so that the two hypotenuses are in line with each other. This will make a bigger right triangle, which is similar to the smaller right triangles - each side is double of the smaller triangles.

When classifiying triangles by angles obtuse triagles have one obtuse angle and what two other angles?
An obtuse angle is greater than 90° (and less than 180° ) The other two angles therefore total less than 90° and so both must be acute angles.
How are acute and obtuse triangles the same?
Similarities between these and all triangles are:They all have 3 sides and 3 angles. The sum of the three angles adds up to 180°.An acute angle is less than 90 degrees. An acute triangle has all three sides are acute.An obtuse angle is more than 90 degrees. An obtuse triangle has one angle which is obtuse, and because of the 180° rule above, the other two angles will be acute.So all triangles will have at least two acute angles.

If the 2 triangles are right triangles, which are congruent to slicing the rectangle on the diagonal, then arrange one on top of the rectangle, and the other to the side, so that the two hypotenuses are in line with each other. This will make a bigger right triangle, which is similar to the smaller right triangles - each side is double of the smaller triangles.
What kind of triangles are there?
There are many kind of triangles. These are the following: Acute, Right, and Obtuse are actual angles. Scalene, Isosceles, and Equilateral are all actual triangles. But, you can have any triangle with any angle. Like a scalene triangle with a Right angle, or an Isosceles triangle with an Obtuse angle.Acute is a triangle with an angle less than 90 degrees. So it is smaller than a Right triangle. To make and Acute triangle, you need at least two Acute angles.Right triangle have at least on right angle. Right angles are angles that re exactly 90 degrees. If you put a cube right where the angle went, both sides would be perfectly straight.Obtuse triangles are triangles with at least one Obtuse angles. They are always bigger than 90 degrees. They are larger than a Right triangle. If you spread your legs apart, you would have an Obtuse angle.Scalene triangles are triangles with all of the sides different lengths. Each side is either longer or shorter, they are never the same.Isosceles triangles are triangles with two sides the same lengths. The other side is either longer or shorter.Equilateral triangles are triangles with ever side the same exact length. They all are exactly the same. If one is different, it's not an Equilateral triangle.
Are all scalene triangles acute triangles?
No, scalene triangles can be obtuse, right or acute triangles. A 3 - 4 -5 right triangle (lengths of the sides) is one example of a right-scalene triangle. In fact, with the exception of the [45°, 45°, 90°] right triangle (which is isosceles) all other right triangles are scalene.
Is it true that Obtuse triangles have one interior angle whose measure is more than 90 degrees?
Yes and their other two angles are acute angles.
How many unique triangles can be made where one angle measures 60 degrees and another angle is an obtuse angle?
Infinitely many can be made. With one angle 60°, that leaves 180° - 60° = 120° as the sum of the other two angles. An obtuse angle is one greater than 90° and less than 180°. Thus as long as one of the other angles is greater than 90° and less than 120°, the other will be 120° less it. Some possible other angles: 100° and 20° 100.5° and 19.5° 100.05° and 19.95° 100.025° and 19.975° There are infinitely many numbers between 100 and 101, therefore there are infinitely many pairs of number whose sum is 120 where one of them lies between 100 and 101 (inclusive, or exclusive - it matter not which). ------------------------------------------ If you meant triangles with angles which are WHOLE numbers, then there are: Smallest obtuse angle = 91° Largest obtuse angle = 119° → there are 119 - 91 + 1 = 29 such triangles.
