Given to look at the triangle and identify their vertices, sides and angles and fill the given table. The triangle 2 is given, The triangle is named as △ NML We need to find their vertices, sides and angles. Vertices is a corner where edges meet and sides are lines. Therefore, vertices = N , M , L and the sides are NM , ML , LN In geometry, an angle can be defined as the figure formed by two rays meeting at a common end point. Therefore, the angles are ∠ NML , ∠ MLN , ∠ LMN Triangle no 3 given, The triangle is named as △ DEF We need to find their vertices, sides and angles. Vertices is a corner where edges meet and sides are lines. Therefore, vertices = D , E , F and the sides are DE , EF , FD In geometry, an angle can be defined as the figure formed by two rays meeting at a common end point. Therefore, the angles are ∠ DEF , ∠ EFD , ∠ FDE Hence, Triangle No. Name of triangle Vertices Sides Angles 1 △ P Q R P , Q , R PQ , QR , PR ∠ PQR , ∠ QPR , ∠ PRQ 2 △ NML N , M , L NM , ML , LN ∠ NML , ∠ MLN , ∠ LMN 3 △ DEF D , E , F DE , EF , FD ∠ DEF , ∠ EFD , ∠ FDE
