Most people, when asked to draw a triangle, would probably draw an acute or maybe a right triangle.
They both have at least two acute angles. Their centroid is not outside the triangle.
They have [at least] two acute angles.
No. All three angles of an acute traingle are less than 90 degrees, so it cannot be a right triangle. The only similarity between them is that right angle triangle has 2 acute angles while acute triangles has 3 acute angles
An equilateral triangle is when all angles and sides are equal throughout the triangle. If the triangle has same sides then it has same angles. Acute triangle is when all angles in the triangle are under 90 degrees. Since all triangles have three angles, and the sum of all angles within any traingle equals 180degrees, we must divide 180degrees by 3 angles.... 180deg/3A= 60deg per angle... This is the only option since there is only one equilateral triangle set of angles (60/60/60). And all the angles are under 90 deg. So in other words an equilateral triangle is an acute triangle.
A right angled triangle has one angle that is 90 degrees. The other two must be acute and may (but need not) be equal to one another. An acute triangle has all its angles less than 90 degrees. They may be all the same, two of them the same or all different. An isosceles triangle has two angles the same (and hence acute). The third angle can be acute, right or obtuse. A scalene triangle has three unequal angles. Two of them must be acute but the third may be acute, right or obtuse.
No. For example a triangle with sides 6, 7 , 8.

Scalene means the triangle has 3 sides unequal length. Acute means the triangle has 3 acute angles (less than 90o). So you should be able to draw a scalene acute triangle pretty easily. An equilateral triangle has all sides the same length and all angles are 60o. If you stretch one side a little, and shrink another side a little you will have a scalene triangle. And as long as you haven't stretched or shrunk the sides too far, it will also still be acute.
In the same way that you bisect an acute triangle. Alternatively, you could extend one of the rays of the obtuse angle so that you have an acute angle. Bisect that angle and then draw a perpendicular to the bisector of the acute angle through the vertex.
No. All three angles of an acute traingle are less than 90 degrees, so it cannot be a right triangle. The only similarity between them is that right angle triangle has 2 acute angles while acute triangles has 3 acute angles
In a acute triangle, all the angles are less than 90 degree's. In a right triangle, one of the angles is 90 degree's, so a triangle cannot be bot acute and right at the same time.
acute, if you are referencing a triangle

right triangle. pretty easy! lol. if it makes a right angle it should be a right triangle. if it is acute. it is an acute triangle, and the same with obtuse. its all simple to remember
A right angled triangle has one angle that is 90 degrees. The other two must be acute and may (but need not) be equal to one another. An acute triangle has all its angles less than 90 degrees. They may be all the same, two of them the same or all different. An isosceles triangle has two angles the same (and hence acute). The third angle can be acute, right or obtuse. A scalene triangle has three unequal angles. Two of them must be acute but the third may be acute, right or obtuse.
No. Similar triangles have all the same angles. An acute triangle can never have an obtuse angle, so the two cannot be similar.
