A triangle with one obtuse and two acute angle is called
1 right angled triangle
2 acute angled triangle
3 obtuse angled triangle
4 none
Explanation:
obtuse angled triangle An obtuse triangle (or obtuse - angled triangle) is a triangle with one obtuse angle (greater than 90176;) and two acute angles. Since a triangles angles must sum to 180176; in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.

What is area of equilateral triangle?
1 \(\frac{3}{4}\text{a}^2\)
2 \(\frac{\sqrt{3}}{4}\text{a}^2\)
3 \(\frac{3\sqrt{3}}{4}\text{a}^2\)
4 \(\frac{\text{a}^2}{4}\)
Explanation:
\(\frac{\sqrt{3}}{4}\text{a}^2\) Area of an equilateral triangle with side 'a' units is

(1, - 1), \(\bigg(-\frac{1}{2},\frac{1}{2}\bigg)\) and (1, 2) are the vertices of a /an__________ triangle.
1 equilateral
2 isosceles
3 right angled
4 scalene
Explanation:
isosceles Distance between the points \((1, 1), \bigg(\frac{-1}{2},\frac{1}{2}\bigg)\) is \(\sqrt{\big(\frac{3}{2}\big)^2\big(\frac{-3}{2}\big)^2} = \frac{3}{\sqrt{2}}\) Similarly, distance between the points \(\big(\frac{-1}{2}\big), (1, 2)\) is \(\frac{3}{\sqrt{2}}\) Similarly, distance between the points (1, - 1),(1, 2) is 3 As two sides are equal,
