Two equilateral triangles are always similar!
No. Similar triangles have all the same angles. An acute triangle can never have an obtuse angle, so the two cannot 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.
Yes, they are.
no think about it
no, it is impossible
Not always, but it can be. Isosceles triangles have two equal sides and therefore two equal angles. An obtuse triangle has one angle exceeding 90º.
Yes, two equilateral triangles are always similar to each other. They have the same number of sides, the same angles and the lengths of the sides between the two triangles are always in the same ratio.
yes. they are always the same but a different scale.
No. A triangle is similar to one that is twice its size but the two are not congruent.
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.
Yes. Corresponding angles of the two triangles are always equal, and lengths of corresponding sides are always in the same ratio.
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.
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.
They are said to be similar but not congruent triangles.
Similar, YES. Congruent, NO.
Spherical triangles as on the earth's surface.
Triangles are classed as: scalene, right angle, obtuse, isosceles and equilateral
