Are two isosceles right triangles always similar?
No
If the vertex angles of two isosceles triangles are congruent are the triangles always similar?
Yes, they are.
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.
Are similar triangles always congruent?
No, congruent triangles are always similar but similar triangles and not always congruent. Imagine that similar triangles can be created on a copy machine enlarge and shrink the image, turn it, even turn it over, the angles remain the same. A congruent triangle must be exactly the same as the original. Hope this helps!
Does an acute triangle have obtuse angles?
No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.
Are two obtuse triangles sometimes always or never similar?
sometimes
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.
Two equilateral triangles are sometimes similar?
Two equilateral triangles are always similar!
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.
Are two isosceles right triangles always similar?
No
If the vertex angles of two isosceles triangles are congruent are the triangles always similar?
Yes, they are.
Can triangles have two obtuse angles?
no think about it
Are there triangles with two obtuse angles?
no, it is impossible
Is that true that if two congruents triangles are always similar?
Yes.
Are two scalene triangles always similar?
yes. they are always the same but a different scale.
How many obtuse triangles are in the jamaican flag?
Two
Are two triangles always the similar?
Nope. You must know what it means to be similar. It means that ALL three angles are the same between two triangles. That been said, you can take any two random triangles, it's very likely that they are NOT similar.
