WebCongruence permits alteration of some properties, such as location and orientation, but leaves others unchanged, like distances and angles. The unchanged properties are called invariants. In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. WebA degree (in full, a degree of arc, arc degree, or arcdegree ), usually denoted by ° (the degree symbol ), is a measurement of a plane angle in which one full rotation is 360 degrees. [4] It is not an SI unit —the SI unit of angular measure is the radian —but it is mentioned in the SI brochure as an accepted unit. [5] WebWe can use the following equation to represent the triangle: x^\circ + 42^\circ + 106^\circ = 180^\circ x∘ + 42∘ + 106∘ = 180∘ The missing angle is 180^\circ 180∘ minus the measures of the other two angles: x^\circ = … check movie which ott platform
