What triangle measures 100 degrees?
an isosceles triangle has an angle that measures 100 degrees.
Keeping this in consideration, what type of triangle has an angle that measures 120 degrees and an angle that measures 30 degrees?
There is a special triangle called an isosceles triangle.

What angle measures 60?
Constructing a 60° angle This construction works by creating an equilateral triangle. Recall that an equilateral triangle has all three interior angles 60°. We use one of those angles to get the desired 60 degree result.

How do you find the measure of an angle?
Using a Protractor The best way to measure an angle is to use a protractor. To do this, you’ll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle’s measurement to the nearest degree.
What is a unique triangle?
The two angles and any side condition determines a unique triangle. Since the condition has two different arrangements, we separate it into two conditions: the two angles and included side condition and the two angles and the side opposite a given angle condition.
How much degrees is an equilateral triangle?
You’ll notice that along with this triangle’s sides, its three angles are also all equal. Since the sum of a triangle’s angles is always 180 degrees, each angle in an equilateral triangle must measure 60 degrees.
How many degrees is a triangle?
How many degrees is an scalene triangle?
How do you find the angle of a triangle given two sides?
- Step 1 The two sides we know are Opposite (300) and Adjacent (400).
- Step 2 SOHCAHTOA tells us we must use Tangent.
- Step 3 Calculate Opposite/Adjacent = 300/400 = 0.75.
- Step 4 Find the angle from your calculator using tan-1
How many degrees is a line?
The angles on a straight line add up to 180 degrees.
Can a triangle have two obtuse angles?
Two obtuse angles by definition mean that there would be two angles of (at least) 91 degrees each. Therefore, a triangle can never have more than one obtuse angle. When an angle of a triangle is 90 degrees, the triangle cannot have an obtuse angle.
How many degrees is a square?
All four angles of a square are equal. (Each is 360°/4 = 90°, so every angle of a square is a right angle.) All four sides of a square are equal.
How many degrees is a quadrilateral?
What is a right angle triangle called?
A right triangle (American English) or right–angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The side opposite the right angle is called the hypotenuse (side c in the figure).
Can a triangle have two right angles?
Answer Expert Verified In Euclidian (flat) geometry the sum of all angles, in a triangle, by definition, must be equal to 180 degrees. So, we can‘t have two right angles in a triangle, only one, because the sum of two other angles must be 90 degrees.
How do you identify a triangle type?
- Acute Triangle: All angles are less than 90°.
- Obtuse Triangle: One angle is greater than 90°.
- Right Triangle: One angle is 90°.
- Equilateral Triangle: 3 equal sides. 3 equal angles.
- Isosceles Triangle: 2 equal sides. 2 equal angles.
- Scalene Triangle: No equal sides. No equal angles.
Is a triangle a polygon?
As you learned in the last lesson, a triangle is the simplest polygon, having three sides and three angles. The sum of the three angles of a triangle is equal to 180 degrees. Triangles are classified by sides and by angles. Move your cursor over the triangles to learn more.
What does obtuse triangle mean?
An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.
What triangle Cannot be drawn?
Triangle Inequality Theorem One According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that you cannot draw a triangle that has side lengths 2, 7 and 12, for instance, since 2 + 7 is less than 12.
What type of angles are in a triangle?
The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees The two sides of the triangle that are by the right angle are called the legs and the side opposite of the right angle is called the hypotenuse.
