What else can I help you with?
An equilateral triangle can be obtuse?
No - an Equilateral triangle - all three angles (and sides) are the same measure, and by the definition of a triangle the sum of all the angles is 180. Therefore, all angles are 60, making it impossible for it to be obtuse.No.
Can a regular triangle have 3 60 degree angles?
Yes, a regular triangle, also known as an equilateral triangle, has three angles that are each 60 degrees. In any triangle, the sum of the interior angles is always 180 degrees, and in an equilateral triangle, all angles are equal, making each one 60 degrees. Thus, a regular triangle indeed has three 60-degree angles.
What kind of triangle is a triangle with the angles 18 90 and 72 degrees?
The triangle contains a 90 degree angle, making it a right-angled triangle.
How do you make a triangle with 2 right angles?
A triangle can not contain two right angles. This is because:A triangle contains three separate anglesThe sum of the angles in a triangle is equal to 180 degreesA right angle is 90 degreesBecause 90 + 90 = 180, that leaves the remaining angle in the triangle at 0 degrees, making the shape not a triangle but a line segment.
What is a triangle measuring 55 degrees 45 degrees and 80 degrees?
A triangle with angles measuring 55 degrees, 45 degrees, and 80 degrees is a valid triangle because the sum of its angles equals 180 degrees. This triangle is classified as an acute triangle since all its angles are less than 90 degrees. Additionally, it does not have any sides of equal length, making it a scalene triangle.

What kind of triangle is a triangle with the angles 18 90 and 72 degrees?
The triangle contains a 90 degree angle, making it a right-angled triangle.
Which triangle has one right angle and two acute angles?
A triangle with one right angle and two acute angles is called a right triangle. In a right triangle, one of the angles measures 90 degrees, making it a right angle, while the other two angles are acute, meaning they measure less than 90 degrees each. The Pythagorean theorem can be applied to solve for the lengths of the sides of a right triangle.

This is because:A triangle contains three separate anglesThe sum of the angles in a triangle is equal to 180 degreesA right angle is 90 degreesBecause 90 + 90 = 180, that leaves the remaining angle in the triangle at 0 degrees, making the shape not a triangle but a line segment.
What triangle has the angles 40 50 and 90 degrees?
The triangle with angles measuring 40, 50, and 90 degrees is a right triangle. In a right triangle, one of the angles is always 90 degrees, making it a right-angled triangle. The other two angles are acute angles, measuring less than 90 degrees each. The sum of the interior angles of any triangle is always 180 degrees.
What is the greatest amount of obtuse angles a triangle can have?
Just the one and the other two angles must be acute making the 3 interior angles adding to 180 degrees
What is a triangle measuring 55 degrees 45 degrees and 80 degrees?
A triangle with angles measuring 55 degrees, 45 degrees, and 80 degrees is a valid triangle because the sum of its angles equals 180 degrees. This triangle is classified as an acute triangle since all its angles are less than 90 degrees. Additionally, it does not have any sides of equal length, making it a scalene triangle.
What is the name of a 20 80 triangle?
A triangle with angles of 20 degrees and 80 degrees is classified as an acute triangle since all its angles are less than 90 degrees. The third angle can be calculated as 180 - 20 - 80 = 80 degrees, making it an isosceles triangle as well, since it has two equal angles of 80 degrees.
Can a right triangle be isosceles?
No, an isosceles triangle can not be a right triangle, because a right triangle has an angle of 90 degrees angle, and two angles of 45 degrees. An isosceles triangle has all acute angles, therefor, making it an acute triangle, so no, an isosceles triangle is not, i repeat not, a right triangle.
What kind of triangle has angles 50 degrees 65 degrees and 65 degess?
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.
The sum of all the angles making up any triangle is 270 degrees?
No, it's 180 degrees
Isosceles triangles equal 180 degrees?
The total sum of angles of a triangle is 180, so only one angle of a triangle can be 90 ( making it a right angled triangle).However the sum of two angles of a triangle can be equal to 90, once again making it a right angled triangle.it is possible that two angle can be equal to 180-The acute angles of a right triangle are complementary.SUPPOSE ABC IS A TRIANGLE, where C = 90, thenA+B+90 = 180,A+B = 180-90or A+B = 90,or A = 90-Bso it's possible.
