It can. An example of an isosceles triangle without any angles greater than 90 would be an equilateral triangle, with all angles equalling 60 degrees. An example with an angle greater than 90 would be a triangle with angles of 100 degrees, 40 degrees and 40 degrees.

You couldn't have an isosceles triangle with 2 angles greater than or equal to 90, as all the angles sum to 180 degrees.

Is a triangle with two congruent legs always a 45-45-90 triangle?

No. The triangle is an isosceles triangle and the angle between the equal sides can be any angle greater than 0° and less than 180°.


What is the maximum vertex angle in an isosceles triangle?

an isosceles triangle can have any vertex angle less than 180 and greater than 0, as long the other two angles are equal. an isosceles triangle with a vertex of 179 degrees would just have the other two angles be 0.5 degrees. A right triangle with matching angles (both 45 degrees) would be both a right triangle and isosceles triangle.


What is an isosceles triangle with angles greater than 90?

In one triangle, there can only be one angle greater than 90 degrees. With that restriction, then the other two angles split the remaining 90 degrees between them. If the split is even, then the triangle is isosceles. There's nothing mysterious or special about it.


Has an isosceles triangle have an obtuse angle?

Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.


Where is the obtuse in the isosceles triangle?

If it were one of the two equal angles it would mean the sum of the triangle's angles would be greater than 180o. It can only be the other angle.


Is an isosceles triangle an example of an acute angle?

For starters, here are the basic rules of triangles.A right angle is 90 degrees.An acute angle is less than 90 degrees.An obtuse angle is more than 90 degrees.A triangle's angles always add up to 180 degrees.An isosceles triangle has two sides that are the exact same length and thus two same angles.Now, an isosceles triangle can have all acute angles. For example, its angles can measure in degrees at 80, 50, and 50. However, isosceles triangles can also have an obtuseangle.For example, consider a triangle with the following angle degree measures: 96, 42, 42.With the rules above in mind, the triangle above is an isosceles triangle because two angles are the same and they both are acute. At the same time, the remaining angle is greater than 90 degrees and so is obtuse. Thus, a single triangle can have both acute and obtuse angles.Similarly, you can have a right triangle that is also isosceles, with the angle degree measurements at 90, 45, and 45.


What is a triangle with one angle greater than right angle?

obtuse triangle


What is the name of the triangle that is greater than 90 degrees?

A triangle that has an angle greater than 90o is an obtuse triangle.


Is an isosceles obtuse triangle possible?

Yes it is possible. Obtuse means the triangle contains an angle which is greater than 90 degrees, and isosceles means the triangle has two sides of the same length. So to prove this in the easiest way possible, you can make a dot on your page, measure 91 or more degrees and draw two equal length lines out at this angle, then connect these two lines to make an obtuse isosceles triangle.


What are the kinds of triangle acording to their angles?

equilateral triangle has all angles of 60 degrees isosceles triangle has only two equal angles scalene triangle have no equal angles acute triangle has all angles less than 90 degrees right angle triangle has one angle of 90 degrees obtuse triangle has one angle greater than 90 degrees right isosceles triangle has 90, 45, 45 degree angles assuming two angles are the same: acute isosceles triangle can range from <90,>45,>45 down to >0,<90,<90 obtuse isosceles triangle can range from >90,<45,<45 up to <180,>0,>0


Two types of triangle?

There are three main types of triangle:Scalene - all angles are different and all sides are different lengthsIsosceles - Two sides are equal in length and the two angles (between the third side and the two sides of equal length) are equalEquilateral - All three angles are equal (at 60°) and all three sides are of equal length.If all angles are less than 90° then the triangle can also be described as an Acute triangle; an equilateral triangle is acute by definition as all angles are 60° which is less than 90°.A Scalene or Isosceles triangle can also be described as a Right angle triangle if one angle is 90° (a right angle); in the isosceles triangle this is the angle between the sides of equal length.A Scalene or Isosceles triangle can also be described as an Obtuse triangle if one angle is greater than 90°; in the isosceles triangle this is the angle between the sides of equal length.


Is an isosceles triangle an obtuse?

It can be but need not be.
