Do two obtuse triangles have to be similar?
No, because they only have the limitations of 91 degrees (lowest obtuse angle) and 179 degrees (highest obtuse angle). Two obtuse angles could be either of them or anything in between.
Is the Pythagorean theorem is true for all similar triangles?
Only right triangles.
Are Isosceles triangles right obtuse and acute?
yes a isosceles triangle has a right,obtuse and acute angle.
Is a triangle 180 degrees or 360 degrees?
Triangles whether acute, obtuse, equilateral or scalene will only ever have angles that add to 180 degrees.
Is all acute triangles similar?
Only if they have the same angles
Are two obtuse triangles always similar?
Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.
Can an acute and obtuse triangle be similar?
No. Similar triangles have all the same angles. An acute triangle can never have an obtuse angle, so the two cannot be similar.
Are two obtuse triangles sometimes always or never similar?
sometimes
Are all equilateral triangles obtuse?
No, none of them are.
Given n points in the plane you draw all possible triangles whose vertices are any three of the given points Atleast how many of them are obtuse-angled triangles?
The least number of obtuse triangles, if all possible triangles are drawn for n points in a plane, is zero. If all the n points lie in a straight line, no triangles are possible and so no obtuse triangles are able to be drawn; thus for any number n, there is a possibility that no obtuse triangles can be drawn, so the least possible number of obtuse triangles drawn is zero.
How many obtuse angles does a obtuse triangle have?
Triangles do not have to have any obtuse angles but they can have one.
Are scalene triangles all obtuse?
No, a scalene triangle is simply a triangle where all angles are not equal and all side lengths are not equal, therefore they can or cannot be obtuse.
Do all triangles have two acute angles?
INCORRECT: No because there is a obtuse triangle and a right triangleCORRECT ANSWERYes all triangles have at least two acute angles. Obtuse triangles and right triangles also have at least two acute angles. They are called obtuse triangles and right triangles because by definition they are triangles with ONE obtuse angle and ONE right angle. So therefore they both have 2 acute angles. Also for an acute triangle, it would have 3 acute angles.
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 two obtuse triangles have to be similar?
No, because they only have the limitations of 91 degrees (lowest obtuse angle) and 179 degrees (highest obtuse angle). Two obtuse angles could be either of them or anything in between.
What triangle has at least one obtuse angle?
-- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it . -- Right triangles, acute triangles, and equilateral triangles don't have any obtuse angles in them.
What types of triangles can have an obtuse angle?
An obtuse triangle
