Answer :-

If the measure of two angles are equal they are

called:-

  • a) straight angles
  • b) Congruent angles
  • c) Interior angle

Step-by-step explanation:

Congruent angles:

Two angles are said to be congruent ( equal ), if their measures are same.

Let's take an example:

Figure 1 :- [ ACB ]

\setlength{\unitlength}{1 cm}\begin{picture}(0,0)\thicklines\put(5,1){\vector(1,0){5.5}}\put(5,1){\vector(1,1){4}}\put(9.4,5){$\bf A$}\put(10.7,0.9){$\bf B$}\put(4.5,0.8){$\bf C$}\put(5.3,0.99){\qbezier(0,0)(1,0)(0.2,0.5)}\put(6.3,1.5){$\bf {60}^{\circ}$}\end{picture}

Figure 2 :- [ PRQ ]

\setlength{\unitlength}{1 cm}\begin{picture}(0,0)\thicklines\put(5,1){\vector(1,0){5.5}}\put(5,1){\vector(1,1){4}}\put(9.4,5){$\bf P$}\put(10.7,0.9){$\bf Q$}\put(4.5,0.8){$\bf R$}\put(5.3,0.99){\qbezier(0,0)(1,0)(0.2,0.5)}\put(6.3,1.5){$\bf {60}^{\circ}$}\end{picture}

Here,

Figure 1 and Figure 2 are congruent angles. As

  • ∠ACB and ∠PRQ are congruent angles because, ∠ACB and ∠PRQ have same measurement.

Know more :-

  • Angle: An angle is a figure formed by two days with the common initial point is called angle.
  • Straight angle: The angle that measures only 180° is called straight angle.
  • An angle formed by two opposite rays is called straight angle.
  • Sum of all the angles in a straight line is always 180°.
