Vertex opposite to the side \(\text{RT}\) of \(\triangle\text{RST}\) is. 7
1 S
2 R
3 T
4 None of these
Explanation:
S Vertex opposite to any side of the triangle is just the facing vertex and not the vertex that is lying on the given line.

If all the three sides of a triangle are equal, the triangle is called:
1 Equilateral
2 Right-angled
3 Isosceles
4 Scalene.
Explanation:
Equilateral A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal.

A triangle in which two sides are of equal length is called ________ triangle.
1 Scalene
2 Equilateral
3 Isosceles
4 Acute-angled
Explanation:
Isosceles Triangle having all sides equal is the Equilateral triangle. Triangle having two sides equal is an isosceles triangle. Triangle having all sides of different length is a scalene triangle.

In Fig. if AB || DE, then the value of x is:
1 25
2 35
3 40
4 45
Explanation:
45 \(\angle \text{ACD}+\angle \text{ACB}=180^\circ\) [Linear angles] \(\Rightarrow 91^\circ+\angle \text{ACB}=180^\circ\) \(\Rightarrow \angle \text{ACB}=89^\circ\) Since, AB || DE \(\angle \text{DEC}=\angle \text{CAB}=46^\circ\) [Alternate angles] Now, \(\angle \text{ACB}+\angle \text{CAB}+\angle \text{ABC}=180^\circ\) [Angle sum property of triangle] \(\Rightarrow 89^\circ + 46^\circ + \text{x}^\circ = 180^\circ\) \(? \text{x}^\circ = 45^\circ\) \(\Rightarrow \text{x} = 45\) Hence, the correct answer is option (d).
