No. The sum of the internal angles of a plane triangle is 180 degrees. If one of the angles is 90 degrees or more, this leaves 90 degrees or less to be distributed between the other two angles which will then both be acute.No because 2 obtuse angles would measure over 180 degrees and the 3 angles of any triangle add up to 180 degrees.
They are both acute angles because they are less than 90 degrees and the 3rd angle is 71 degrees which is also an acute. The triangle is a scalene triangle.
No because the three interior angles of any triangle always add up to 180 degrees.
An equilateral triangle must be acute because each angle is equal to 60 degrees. If all three angles are less than 90 degrees then a triangle is acute.
1 Angles are measured in degrees, minutes and seconds 2 Angles greater than 0 but less than 90 degrees are acute 3 Angles of 90 degrees are right angles 4 Angles greater the 90 but less than 180 degrees are obtuse 5 Angles greater than 180 but less than 360 degrees are reflex 6 Angle of 360 degrees is a full rotation 7 Triangles are 3 sided polygons 8 Triangles have 3 inside angles that add up to 180 degrees 9 Triangles have 3 outside angles that add up to 360 degrees 10 Triangle that is scalene has 3 different acute angles 11 Triangle that is a right angle triangle has a 90 degree angle and 2 acute angles 12 Triangle that is obtuse has 1 obtuse angle and 2 acute angles 13 Triangle that is isosceles has 2 equal base angles and 2 equal sides 14 Triangle that is equilateral has 3 equal inside angles and 3 equal sides 15 Triangles have no diagonals 16 Triangles will tessellate leaving no gaps or overlaps 17 Triangle's area is 0.5*base*perpendicular height 18 Triangle's perimeter is the sum of its 3 sides 19 Triangle as a right angle triangle is subject to Pythagoras' theorem 20 Triangles are subject to the rules of trigonometry 21 Triangles are the corner stones of all other polygons
A triangle with all angles measuring less than 90 degrees?That's an 'acute' triangle.
Yes. An acute triangle has three angles that individually are less than 90 degrees. Remember you can add the internal angles together in a triangle and they will always add up to 180 degrees.
A scalene triangle has 3 interior acute angles less than measuring90 degrees but they add up to 180 degrees
It is an acute triangle
An acute triangle.
An acute triangle is one in which all interior angles are less than 90 degrees.
An ACUTE triangle is A triangle with all angles that are less than 90 degrees
An acute triangle has all angles less than 90o.
This would be an acute triangle. If all three angles are 60 degrees, then it is equiangular.
An acute triangle
An acute(-angled) triangle.
When all of its angles are less than 90 degrees.
