What are the sums of the angles in a triangle?
60 degrees for an equilateral triangle, but it depends on what kind of triangle you're dealing with.
What is the sum of the measures of the three angles of a scalene triangle?
In a scalene triangle, the angle sum is still 180 degrees. What defines a scalene triangle is that it has three sides with different lengths, and therefore, also different angles. It can be a right triangle for example, with the angles 30, 90, and 60 degrees. It's angle sum always sums up to 180 as in all triangles. Note: It doesn't have to be a right triangle. It can be any kind of triangle as long as it has three different angles and sums up 180 degrees.
Where did the Pascal Triangle first appear?
Hindu studies of combinatorics but Pascal discoevered more uses for it. If you add up the diagonals of Pascal's triangle, the sums are the entries of the Fibonacci Sequence.
Why every angle in an equiangular triangle must measure 60 degree?
because the sums of all angles in a triangle must always be 180. So with 3 equal angles they all have to be 60.
Can a triangle contain two 90 degree angles?
No, because a triangle needs three angles whose sums add up to 180 degrees. Since you already have the 180 degrees in 2 angles there is no room for a third. Without three angles, a shape cannot be a triangle.
What are the sums of the angles in a triangle?
60 degrees for an equilateral triangle, but it depends on what kind of triangle you're dealing with.
What does equilateral triangle have in common with a scalene triangle?
The sums of their interior angles both total to 360 degrees.

What is the sum of the numbers in the 5th row of pascals triangle?
depends. If you start Pascals triangle with (1) or (1,1). The fifth row with then either be (1,4,6,4,1) or (1,5,10,10,5,1). The sums of which are respectively 16 and 32.

Does the square and trapazoid have the same sum of interiorangles?
Yes. They are both quadrilaterals and the sum of the interior angles depends only on the number of sides.
What is on feature of a rhombus?
It is a quadrilateral with 4 equal sideswith 2 equal obtuse and 2 equal acute interiorangles that add up to 360 degrees.
How do you do sums?
The answer will depend on what kind of sums.
What are some of Pythagoras contributions to math?
Pythagoras is, of course, best remembered for the Pythagorean Theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sums of the squares of the other two sides.
How many sides in a polygon whose sum of the interiorangles is 1800?
Sum_interior_angles = (number_of_sides - 2) x 180o → number_of_sides = sum_of_interior_angles ÷ 180o + 2 = 1800o ÷ 180o + 2 = 12
