the prisms which are used in binoculars are acute, right,obtus,equaliteral
​

Answer 1

Answer:

Explanation:

Binoculars have a pair of prisms (large wedges of glass) inside them to rotate the image through 180 degrees. One prism rotates the image through 90 degrees (flips it onto its side), then the next prism rotates it through another 90 degrees (flips it onto its side again), so the two prisms effectively turn it upside down. The prisms can either be arranged in a back-to-back arrangement or at 90 degrees.
