How do you know if a triangle is obtuse or acute?
An acute triangle has three angles that each measure less than 90 degrees. An obtuse triangle is a triangle with one angle that is greater than 90 degrees.
How do you find the length of a triangles side?
The Pythagorean theorem states that, in a right triangle, the square of the length of the hypotenuse (the side across from the right angle) is equal to the sum of the squares of the other two sides. So if the length of the hypotenuse is c and the lengths of the other two sides are a and b, then c^2 = a^2 + b^2.
What type of triangle has side lengths 2 √ 12 and √ 19?
If the side lengths are 2, √12, and √19, the triangle is SCALENE, since all the sides have different lengths.
How do you know if a triangle is acute or side lengths?
It is an acute triangle. To determine whether the triangle is acute, right, or obtuse, add the squares of the two smaller sides, and compare the sum to the square of the largest side. Since this sum is greater, the triangle is acute.
Which type of triangle is this triangle with length of sides 7 cm 8 cm and 9 cm?
scalene triangle
Explanation: (a) Triangle with lengths of sides 7 cm, 8 cm, and 9cm will have all its sides of different lengths. Hence, it will be a scalene triangle.
What is the length of the triangle?
The Law of Sines says that for all angles of a triangle, the ratio of the sine of that angle to its opposite side will always be the same. The length of side c is 2.98. The Law of Cosines says you can determine the length of any triangle side if you know its opposite angle and the lengths of the other two sides.
What is the length of two sides of a right triangle?
Two sides of a Right Angled Triangle are 15 cm and 17 cm. Two sides of a right angled triangle are 15 cm and 17 cm.
What are the sides of a triangle in cm?

What is the median to side B(TB) in triangle ABC?
Median to side b (tb) in triangle ABC is 12 cm long. a. What is the distance of the center of gravity T from the vertex B? b, Find the distance between T and the side b. Three circles of radius 95 cm 78 cm and 64 cm is mutually tangent.
What are the sizes of the angles of the triangle ABC?
The sizes of the angles of the triangle ABC are α = 35° and β = 48°. Find the magnitudes of all angles of triangle A “B” C “. In triangle ABC, the magnitude of the internal angle gamma is equal to one-third of the angle alpha. The size of the angle beta is 80 degrees larger than the size of the gamma angle.
