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.
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.
What types of triangles can have an obtuse angle?
An obtuse triangle
What is he sum of the angles of an obtuse triangle?
The sum of the interior angles on an Obtuse Triangle is 1800 . This is true of ALL triangles.
How many sides does obtuse triangle have?
All triangles have 3 sides.
Are all obtuse triangles similar?
No not all obtuse triangular are similar. :)
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.
Which shapes have an obtuse angle?
Oh, dude, obtuse angles are like those chill angles that are greater than 90 degrees but less than 180 degrees. So, shapes like obtuse triangles, obtuse trapezoids, and obtuse pentagons totally rock those angles. Just imagine them lounging around, being all nonchalant and stuff.
