There are 180 degrees in a triangle - the sum of the angles totals 180 . So there can only be on 90 angle. The other two angles must add up to 90. Pythagoras theorem states " The square of the hypotenuse of a RIGHT ANGLED (90 degrees) triangle equals the sum of the squares on the other two sides". So if you have a 3-4-5 or a 5-12-13 triangle and their multiples etc, you will have a triangle with a 90 degree angle.

Can a triangle have 1 obtuse angle?
A triangle can only have 1 obtuse angle. Obtuse - greater than 90 degrees. Since a triangles 3 angles add up to 180 degrees, only 1 angle can be obtuse. Right triangle 90 degrees and 2 - 45 degree angles. Perfect? triangle has 3 - 60 degree angles.
Can a quadrilateral have two angles that measure 90 degrees?
yes!! a square! a squares angles are all 90 degrees. and a quadrilateral with 2 90 degree angles, and 1 with 40 one with 50. very possible.
To make sure that a given parallelogram is a rectangle at least how many of its angles must measure 90?
You need only 1 90 degree angle.
An isosceles triangle has 1 angle equal to 90 degrees what are the other two angles?
An isosceles triangle has two equal angles. All the angles of a triangle add up to 180º There can not be another angle with 90º as that would mean the last angle was 0º, so the other two angles must be 45º each.
What is the greatest number of right angles that a triangle can contain?
1 (APEX) A triangle is formed by three lines. If the ends of two lines meet to form a right-angle (90 degrees), the third line can only form angles less than 90 degrees. 90 + 45 + 45 = 180 the three angles must total 180 degrees.
How many 90 degree angles does an acute triangle has?
1
Can a triangle have 1 obtuse angle?
A triangle can only have 1 obtuse angle. Obtuse - greater than 90 degrees. Since a triangles 3 angles add up to 180 degrees, only 1 angle can be obtuse. Right triangle 90 degrees and 2 - 45 degree angles. Perfect? triangle has 3 - 60 degree angles.
Can a triangle have more than 1 acute angles?
YES IT CAN.ACTUALLY A TRIANGLE IT NOT A ACUTE TRIANGLE UNLESS ALL ANGELS ARE ACUTE ANGLES. ACUTE ANGLES ARE LESS THAN 90 DEGREE.
What is a characteristic of a triangle right triangle and obtuse triangle?
A right angle triangle has a 90 degree angle and 2 acute angles An obtuse triangle has 1 obtuse angle and 2 acute angles
A right triangle is a triangle that has?
1 angle of 90 degrees two sides of equal length, and a hypotenuse 2 angles (not including 90 degree one) that are equal
What is 30-60-90 right triangle?
A 30-60-90 right triangle is one in which the three angles of the triangle 30, 60 and 90 degrees. The length of the sides of such a triangle have the ratio 1:2:square root of 3. The 1 is opposite the 30 degree angle, the 2 is opposite the 60 degree angle and the square root of 3 is opposite the 90 degree angle.
A right angle has one angle that measures 16 degrees what are the messures of the other two angles?
A right triangle will always have 1 90 degree angle and the angles of a triangle always add up to 180. Therefore, one of the other angles will be 90 and one will be 180-90-16=74.
How do you separate a triangle into other triangles?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and are classed as follows- 1 Scalene triangle has 3 different acute angles 2 Right angle triangle has a 90 degree angle and 2 acute angles 3 Obtuse triangle has 1 obtuse angle and 2 different acute angles 4 Isosceles triangle has 2 equal acute angles and 1 other angle 5 Equilateral triangle has 3 equal 60 degree angles
What are the names of the triangles and how can you tell?
right triangle forms a 90 degree angle scalene triangle has no congruent sides isosceles triangle has at least 2 congruent sides equilateral triangle has 3 congruent sides acute triangle all angles measure less than 90 degrees and the obtuse triangle contains 1 obtuse angles.
How many angles does a right triangle have?
A right triangle has only one right angle (a 90 degree angle), by definition. The sum of the other two angles equals 90 degrees, so the sum of all three angles is 180 degrees. Every triangle, right triangle or not, has three angles whose sum is 180 degrees.A right angle triangle has only 1 right angle which measures 90 degrees
Classification of triangles according to the interior angles?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees:- Right angle triangle has a 90 degree angle and 2 acute angles Scalene triangle has 3 different acute angles Obtuse triangle has 1 obtuse angle and 2 different acute angles Isosceles triangle has 2 equal angles and a 3rd angle that all add up to 180 degrees Equilateral triangle has 3 equal 60 degree angles
Can a right triangle have two angles that measure 38 and 54 degrees?
No. A right angle triangle means the total sum of the interior angles is 180 degrees and also there is a right angle (90 degree), meaning that the sum of the other 2 angles must be 90 degree (1 degree difference is not allowed)
