Side c and angle C have different measures. In the isosceles acute triangle above, sides a b and angles A B. The figure below shows an isosceles acute triangle. The three sides of a scalene triangle are all different lengths, and the three angles are also all different. An isosceles acute triangle is a triangle that has two sides of equal length and whose angles are all less than 90. Scalene triangle: A scalene triangle is a triangle that has no sides with the same length.An equilateral triangle is always an acute triangle. The three equal sides of an equilateral triangle are called the base of the triangle, and the three angles are all 60 degrees. Equilateral triangle: An equilateral triangle is a triangle that has all three of its sides with the same length.An isosceles triangle can be acute or obtuse, depending on the measure of its angles. The two equal sides are called the base of the triangle, and the third side is called the altitude. Isosceles triangle: An isosceles triangle is a triangle that has two sides with the same length.The other two angles of an obtuse triangle are both acute angles, which means that obtuse triangles are not acute triangles. In our calculations for a right triangle we only consider 2 known sides to calculate the other 7 unknowns. Obtuse triangle: An obtuse triangle is a triangle that has one of its angles measuring more than 90 degrees. An isosceles triangle is a special case of a triangle where 2 sides, a and c, are equal and 2 angles, A and C, are equal.The other two angles of a right triangle are acute angles, which means that right triangles are also acute triangles. In the figure above, the two equal sides have length b and the remaining side has. ![]() This angle is known as the right angle, and it is denoted by a small square symbol. An isosceles triangle is a triangle with (at least) two equal sides. Right triangle: A right triangle is a triangle that has one of its angles measuring exactly 90 degrees.Acute triangle: An acute triangle is a triangle that has all three of its interior angles measuring less than 90 degrees.Acute angle: An acute angle is an angle that measures less than 90 degrees.Triangle: A triangle is a three-sided polygon with three straight sides.These triangles are known for their sharp, pointed appearance, and they have a number of important properties and characteristics that make them unique among the different types of triangles. In other words, all three angles of an acute triangle are acute angles. All congruent triangles are similar, but these triangles are not congruent.Acute triangles are a type of triangle that have all three of their interior angles measuring less than 90 degrees. The correct answer is \(\ \triangle A B C\) and \(\ \triangle D E F\) are neither similar nor congruent. ![]()
