What does the word vertical and opposite angles mean?
vertical angles are when you have an "x" made by intersecting lines and the angles in it are vertical angles. Opposite angles are when you have the x, the angles are on directly opposite sides. --->x<--- those are opposite of each other. therefore they are opposite angles. the arrows are pointing at them
What is the measure of 2 complementary angles if the difference between the angles is 12?
complementary angles add up to 90 degrees x+y=90 y=x+12 x+x+12=90 2x+12=90 2x=78 x=39 x+39=90 x=51 so the angles are 39 degrees and 51 degrees
3 angles add up to a right angle what are the angles?
The right angle = 90 degree. If x is an angle and if these 3 angles are equal then x + x + x = 90 3x = 90 x = 90/3 x = 30 degree So, the angle is 30 degree each.
What are the angles of a parallelogram when two of its interior angles are 2x degrees and x degrees?
If: 2x+2x+x+x = 360 degrees then x = 60 degrees. Therefore angles are: 60 degrees, 60 degrees, 120 degrees and 120 degrees
What size angles does a right angle triangle have?
Let x be any number such that 0 < x ≤ 45 The a right angled triangle has angles of 90, x and 90-x degrees.
