A triangle with sides of 7, 8, and 15 has interior angles of 0, 0, and 180 degrees,
and it looks like a straight line.

Do Obtuse triangles have the same sides?
No That would be an equilateral triangle
What is a shape with no congruent sides and one of it's angles is obtuse?
An obtuse scalene triangle would fit the given description
Can an obtuse triangle have equal sides?
if you mean ALL sides equal then no, because for a triangle to have ALL equal sides all angles must be equal (60 degrees), and an obtuse triangle must have an angle with 91 or more degrees. but if you mean TWO sides equal then yes. for example, a triangle with angles 40, 40 & 100 degrees would have two equal sides.
Is it possible for one triangle to be both an obtuse and scalene?
Yes. A scalene triangle is one in which all sides and angles are different. An obtuse triangle is one in which the largest angle is greater than 90o. An example of an obtuse scalene triangle would be one with angles 100o, 50o & 30o.
It has 1 angle greater than a right angle?
That would be an obtuse triangle. In standard euclidean space any triangle with one angle greater than 90 degrees (a right triangle) is an obtuse triangle, and any triangle where none of the angles is 90 degrees or more is an acute triangle.Of course, polygons with more than three sides are apt to have any number of right, acute and/or obtuse angles.
A triangle with two congruent sides and an angle of 104 degrees is?
A triangle with two congruent sides is isosceles. A triangle with an angle of 104 degrees is obtuse. So you would have an obtuse isosceles triangle.
Do Obtuse triangles have the same sides?
No That would be an equilateral triangle
Why is it impossible for a triangle to have more than one obtuse angle?
It would have four sides?

How can you tell if 3 sides of a triangle are acute or obtuse?
First you would square the length of each of the sides. You'd add the squares of the smaller two numbers. If they are smaller than the square of the biggest side, then the triangle is obtuse. If their sum is bigger, then the triangle is acute. If they are equal, then the triangle is a right triangle.Example:length of sides-23, 34, 49232+342__492529+1156__24011685
How many acute sides does an acute triangle have?
First: Sides are not acute or obtuse. ANGLES are acute or obtuse. An acute triangle has to have all angles acute. Examples: 60, 60, 60 70, 60, 50 45, 50, 85 45, 45. 90 30, 60, 90 But if one of the angles is obtuse (>90 degrees), then the other two must be acute. Of course, *this* triangle would not be called an acute triangle, because one of its angles is abtuse; it would be called an obtuse triangle.
Does a triangle have 1 obtuse angle and 2 acute angles?
That would be an obtuse triangle.
How would you use obtuse in a sentence?
That triangle is not a acute, its an obtuse.
Can a scalene triangle be a obtuse triangle?
Yes, indeed. Imagine a scalene triangle sitting on its longest side. If you could push the pointy part on top down, it would eventually become an obtuse triangle.
Can a triangle have an angle that measures 179 If so what type of triangle would it be?
Yes, if we try to make a triangle with the obtuse angle 179 degree, the remaining sides will have to add up to 1 degree which makes each of them equal to 0.5 degree.. So this is an isosceles triangle which looks like A line.
