Acute.
yes a isosceles triangle has a right,obtuse and acute angle.
If it has 2 equal acute angles and 1 obtuse angle then it is an isosceles triangle.
An isosceles triangle can be acute, obtuse, or right, depending on the measure of its angles. If all angles are less than 90 degrees, it is an acute isosceles triangle. If one angle is greater than 90 degrees, it is an obtuse isosceles triangle. If one angle is exactly 90 degrees, it is a right isosceles triangle.
Only when it has 2 equal acute angles and 1 obtuse angle that it is an isosceles triangle
If it has 2 equal acute angles and 1 obtuse angle then it is an isosceles triangle.
An obtuse triangle or an isosceles triangle if the 2 acute angles are equal in size
yes
yes
yes
There are FOUR(4) different types of triangle. EQUILATERAL ; All sides the same length , and all angles at 60 degrees. ISOSCELES ; Two sides the same length, and two angles of the same value. RIGHT-ANGLED ; Three sides of DIFFERENT lengths or two sides the same length, MUST contain a right-angle (90 degree). SCALENE ; All three sides of different length, and all three angles of different values. For ALL triangles drawn in 2-dimension , the sum of the interior angles must be 180 degrees. NB for a triangle drawn across a 3-dimensional surface (sphere), the sum of the interior angles may be greater than 180 degrees.
Only when it has 1 obtuse angle and 2 equal acute angles can it be an isosceles triangle.
It is an obtuse triangle having 1 obtuse angle and 2 different acute angles Or it is an isosceles triangle having 1 obtuse angle and 2 equal acute angles
