An isosceles triangle has angles of 75, 75 and 30 degrees.
The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
Total sum of angles in a triangle is equal to 180 degrees . Right triangle has a 90 deg. angle so 180-90= 90-30 = 60. The three angles are 90 60 and 30 degrees. == ==
It doesn't matter what type of triangle it is, or the length of the sides. The sum of the interior angles of a triangle always adds up to 180 degrees
An isosceles triangle, because the angles of a triangle add up to 180 and you already know that one angle measures 120 degrees, the other is 30, and so the unknown angle must also be 30 degrees. Since two of the angles are the same, two of the sides are going to be the same, making it an isosceles triangle.
No. An acute triangle only has angles less than 90 degrees. A triangle with a 130 degree angle is obtuse.
A right angles triangle, as one of the angles in the triangle is 90 degrees.
A right angled scalene triangle
An isosceles triangle
The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
Total sum of angles in a triangle is equal to 180 degrees . Right triangle has a 90 deg. angle so 180-90= 90-30 = 60. The three angles are 90 60 and 30 degrees. == ==
It doesn't matter what type of triangle it is, or the length of the sides. The sum of the interior angles of a triangle always adds up to 180 degrees
All the angles of a triangle add up to 180 degrees. In a right triangle one of the angles must be 90 degrees and the other two can be any combination that adds to 90, such as 30 degrees and 60 degrees.
Since the sum of the three angles is 180 degrees, the third angle will be 180 - (30+50) = 100 degrees. The triangle will, therefore, be obtuse.
The third angle has to be 90 degrees so it would be a right angle triangle.
It is an isosceles triangle having 2 equal angles of 30 degrees and an apex angle of 120 degrees
An isosceles triangle, because the angles of a triangle add up to 180 and you already know that one angle measures 120 degrees, the other is 30, and so the unknown angle must also be 30 degrees. Since two of the angles are the same, two of the sides are going to be the same, making it an isosceles triangle.
A triangle with angles that measure 30, 60, and 90 degrees is a special type of right triangle known as a 30-60-90 triangle. In this triangle, the side opposite the 30-degree angle is half the length of the hypotenuse, and the side opposite the 60-degree angle is √3 times the length of the side opposite the 30-degree angle. This relationship is based on the properties of trigonometry and the ratios of the sides in a 30-60-90 triangle.
