What classification of triangle has both line symmetry and rotational symmetry?
Only an equilateral triangle has rotational symmetry.
What are the two general classification of plane triangle?
1.tri- just like 3 2-Angle- just an angle thats classification for yas all lol
What is the classification of a triangle with sides of length 5 inches 12 inches and 13 inches?
A right angle because it complies with Pythagoras' theorem.
Are 20 and 48 and 52 the side measurements of a special right triangle?
A right-angled triangle can indeed consist of sides of 20cm, 48cm, and 52cm. 20, 48, 52 are a valid Pythagorean triple, since 202+482=522.
The sum of the perimeters of two congruent triangles is three times the perimeter of the first triangle?
Let's denote the perimeter of the first triangle as P. Since the triangles are congruent, the perimeter of the second triangle is also P. The sum of their perimeters is then 2P. According to the given statement, this sum is three times the perimeter of the first triangle. So we have the equation 2P = 3P. Simplifying, we find that P = 0, which is not a valid solution. Therefore, there is no triangle for which the sum of the perimeters of two congruent triangles is three times the perimeter of the first triangle.
