uh...yea definitely because the other two can't be 90 degrees or more because it all won't add up to 180 degrees!

How do you classify a triangle by its angles?
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
Classify the triangle with sides 10 13 19 as acute right or obtuse?
In a right triangle, a2 + b2 = c2, where c is the longest side. If the square of the longest side is more than the sum of the other two squares, the triangle has an obtuse angle. If it is less, all angles are acute.
If a triangle has one obtuse angle then the other two angles are acute?
Yeah, they have to be. The sum of the interior angles of a triangle is always 180. If one angle is greater than 90, then the remaining two's sum cannot be.
When two right triangles are similar if an acute angle of one triangle is congruent to an acute angle of the other triangle?
this is true
What does a right acute triangle look like?
Such a triangle would presumably have one right angle, and two acute angles. A right angle has a measure of 90 degrees; an acute angle has a measure of less than 90 degrees. Since both of the other two angles in a right triangle must be acute angles, you'd think at first that every right triangle must be a right acute triangle. But when you go and look up the definition of an "acute triangle", it turns out to be a triangle in which all three angles are acute. So the fact is that there's no such thing as a right acute triangle, because the 90-degree angle in a right triangle is not acute.
Can a triangle with a obtuse angle have two acute angles?
Yes. A triangle can have only one obtuse angle. The other two angles will always be acute.
Is a triangle a Acute Angle Obtuse Angle Right Angle?
A triangle is not an angle. A triangle is made of three angles. -- All three of them can be acute, but they don't need to be. -- One of them can be obtuse but doesn't need to be. -- One of them can be a right angle but doesn't need to be. -- If any angle in the triangle is right or obtuse, then the other two need to be acute.
Is an obtuse triangle a right triangle?
its a triangle * * * * * No, it an obtuse triangle is not a right angle triangle. An obtuse angled triangle has one angle which is greater than 90 degrees and the other two are acute. In a right angled triangle, the largest angle is 90 degrees while the other two are acute. So one cannot be the other.
What is a triangle contanining one obtuse angle?
If the other two acute angles are of different sizes then it is an obtuse or a scalene triangle.
How many obtuse angles are there in a obtuse triangle?
There is one obtuse angle, and the other two are acute angle because in all the whole triangle is 180 degrees.
How do you classify a triangle by its angles?
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
How do you draw an obtuse scalene triangle?
One angle must be an obtuse angle and the other two angles must be acute angles
Use obtuse triangle in a sentence?
In an obtuse triangle, one angle is obtuse and the other two are acute. "The buildings are arranged in an obtuse triangle and occupy most of the long, thin parcel of land."
What figure shows a triangle with no sides congruent and 1 obtuse angle?
An obtuse triangle whose other two angles will be acute angles
What is a triangle that has exactly one obtuse angle?
It could be an isosceles triangle providing that the other 2 acute angles are equal otherwise it is just an obtuse triangle
How is an acute triangle different from both an obtuse triangle and a right triangle?
An acute triangle has no angle of 90 degrees or more. A right triangle has one angle of 90 degrees; the other two are less than 90 degrees. An obtuse triangle has one angle between 90° and 180°; the other two are less than 90°.
Is a acute triangle an isosceles?
If it has 2 equal acute angles and 1 obtuse angle then it is an isosceles triangle.
