What is the measure of other 2 angles of isosceles triangle if 1 angle is 55 degree?
It depends on whether the 55 degree angle is the odd-one-out or not.If it is, then the other two angles must be the same, and they must add up with 55 to be 180. (All angles of a triangle must add up to 180o) So we get the equation:2x+55=1802x=125x=62.5If the 55o angle is congruent with another angle, that means that there are two angles that are 55 degrees. So if we define the other angle as x, we get:x+2(55)=180x+110=180x=70.So if x is the odd one out, then the angles are 55-62.5-62.5If x not is the odd one out, then the angles are 55-55-70
What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 70 degrees and its congruent sides each measure 15 cm?
When finding the angles, the length of the sides is irrelevant in this case.Let the triangle be ABC with ∠A the vertex and BC the base; the real question is whether you have the isosceles triangle "drawn" and labelled with the equal sides:either side of the "vertex" making the equal angles ∠B and ∠CThe equal sides are AB and AC; the base being the odd length means the angles at each end of it are the same, thus: vertex_angle = 180o - 2 x 70o= 40othe base and one side to the vertex equal (say sides AB and BC) and the other side different (AC) making the equal angles ∠A and ∠C70o angle is between the sides of equal length (∠B):The vertex is one of the two equal angles: vertex_angle = (180o - 70o) ÷ 2= 55o70o angle is between the odd side and the base (∠C):The vertex angle (∠A) is the same as the given angle (∠C), that is 70o Isosceles triangles are often drawn in the first case, but it is not necessarily so!
Does right obtuse scalene or acute not belong?
Scalene is the odd-one out - it's a type of triangle. The others are types of angles !

If the lengths of a three sided triangle are 4 7 and 8 is the triangle a right triangle?
No. For it to be a right angle triangle, 42 + 72 = 82. However, the left side is odd and the right side is even and so cannot be equal; thus the triangle cannot be right angled.

What shape has only two angles that measure the same?
2-D: Isosceles triangle would be my best answer. There isn't a 2-D shape with only two angles, so I'll assume your asking for the shape with two congruent angles and all other angles are different. That would be an isosceles triangle. One angle is unique, the other two are congruent. But, that isn't the only one. So long as a shape has an odd number of sides this can happen. 3-D: a cylinder only has two angles, and they're both right angles.

Can you have line of symmetry but not rotational symmetry?
Yes. An isosceles triangle, for example, is symmetric about the bisector of its odd angle but has no rotational symmetry.

No. For it to be a right angle triangle, 42 + 72 = 82. However, the left side is odd and the right side is even and so cannot be equal; thus the triangle cannot be right angled.

Which is the odd one out of triangle square or hexagon?
Triangle: The other shapes have an even number of sides. Square: The numbers of sides on the other two is divisible by 3 Hexagon: For sides of a fixed length, the other two shapes are rigid structures (the square can distort to a rhombus but then it is no longer a square.) or Triangle: It can have all acute angles. Square: It can (must ) have all right angles. Hexagon: It can have all obtuse angles.
How are equilateral isosceles and scalene different?
Equilateral triangles have all sides and angles equal, isosceles triangles have two sides and angles equal, and scalene triangles have no sides or angles equal. In other words, equilateral triangles are a special case of isosceles triangles, and isosceles triangles are a special case of scalene triangles.
