Are some right triangles are isosceles triangles?
Yes.
Does every triangle have to have an obtuse angle?
no Not every triangle has to have one. Some triangles may be acute, meaning that none of their angles are over 90. Some triangles may be right, meaning that there is one right angle. Although some triangles may be obtuse, not all triangles are obtuse.
Do isosceles triangles have all equal sides?
Some people classify isosceles triangles as having at least two equal sides, while other say that they must have exactly two equal sides. So, depending on your definition, some isosceles triangles may have all equal sides, but equilateral triangles always have three equal sides.
What are some triangles?
isocles, equilateral, obtuse, acute, scalene, right
How are equilateral isosceles and scalene different?
And Equilateral Triangle has three EQUAL sides. Basically just your ordinary triangle. The Isosceles triangle usually has TWO equal sides, and one odd side,( not the same size in degrees.) A scalene Triangle also has TWO of the same sides, BUT- Its degrees are usually always different. I'll show you some examples. The first example below is an isosceles Triangle. The 2nd is the Scalene Triangle... Hope I helped...
Some obtuse triangles are scalene?
Obtuse triangles can also be scalene if none of the sides are of equal length. Otherwise, it is an isosceles triangle.
Are some isosceles triangles equilateral triangles?
All isosceles triangles are not equilateral triangles
What are some different triangles?
You have acute, right, and obtuse triangles when referring to the measure of the largest angle, and you have equilateral, isosceles, and scalene triangles when referring to the congruency of the triangle's sides.
Some equilateral triangles are not isosceles?
All isosceles triangles are not equilateral triangles
How do you spell the kinds of triangles?
Some types of triangles are: scalene triangle equilateral triangle isosceles triangle acute triangle right triangle obtuse triangle
Are some scalene triangles also isosceles triangles?
Scalene triangles those triangles in which all the sides are of different lengths, but in isosceles triangles two sides of the triangle are equal in length. Therefore, no scalene triangle can ever be isosceles.
Are some right triangles are isosceles triangles?
Yes.
Do some triangles have one obtuse angle and two acute angles?
Yes. For example, an isosceles triangle with one angle of 120 degrees, and two of 30 degrees.
Does every triangle have to have an obtuse angle?
no Not every triangle has to have one. Some triangles may be acute, meaning that none of their angles are over 90. Some triangles may be right, meaning that there is one right angle. Although some triangles may be obtuse, not all triangles are obtuse.
Does a musical triangle have to be equilateral?
No, some early musical triangles were isosceles triangles, most modern musical triangles are equilateral.
Do isosceles triangles have all equal sides?
Some people classify isosceles triangles as having at least two equal sides, while other say that they must have exactly two equal sides. So, depending on your definition, some isosceles triangles may have all equal sides, but equilateral triangles always have three equal sides.
Some triangles have two obtuse angles and one acute angle?
Spherical triangles as on the earth's surface.
