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 an ACUTE triangle. , because all three angles are less then 90 degrees. Being equilateral , all three angles are 60 degrees. To draw an Equilateral Triangle, you need a ruler , pencil and compass. #1 ; draw a straight line , say 6 inches ( 15 cm). #2 ; Open the compass pointers to the same distancei. (6 ins. ( 15 cm) #3 ; placing the compass point on one ends of the straight line, and draw an arc. (curve). #4 ; Keeping the compass point open to the same distance, place the point on the other end of the straight line, and draw another arc, so that the two arcs cross. #5 ; with the ruler draw a straight line from one end of the base straight line to where the arcs cross. #6 ; from the other end of the same base line, draw another straight line from that point to where the arcs cros.. #7 ; if done correctly, you should see an equilateral 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.
