Theorems on related angles:
Theorems on related angles:If a ray stands on a line, then the sum of adjacent angles formed is 180°. Given: A ray RT standing on (PQ) ⃡ such that ∠PRT and ∠QRT are formed. ...
Theorems on related angles:If a ray stands on a line, then the sum of adjacent angles formed is 180°. Given: A ray RT standing on (PQ) ⃡ such that ∠PRT and ∠QRT are formed. ... The sum of all the angles around a point is equal to 360°. ...
