Question

2
State which of the following pairs of triangles are congruent. If yes, write them in symbolic form (you may
draw a rough figure).

(a) APOR: PO = 3.5 cm, QR = 4.0 cm, 20 = 60°
ASTU: ST = 3.5 cm, TU =
3.5 cm, TU = 4.0 cm, T = 60°

(b) AABC: AB = 4.8 cm, ZA= 90°, AC
= 6.8 cm
AXYZ YZ = 6.8 cm, 2X = 90°, ZX = 4.8 cm
please answer me step by step please friends ​

Answer 1

Answer:

Euler's formula for solids ⇒ Faces+ Vertices− Edges =2

The given solid in the image is a Cuboid

∴ Faces of the cuboid =6

Vertices=8

Edges =12

putting these values in Euler's formula ⇒6+8−12=2

Hence, Verified.
