Answer:
a) 90°
b) (d) The angle at the circumference in a semicircle is a right angle
Step-by-step explanation:
An inscribed angle has half the measure of the arc it subtends.
__
Angle ABC is inscribed in a semicircle and subtends an arc of 180°, so has a measure of 180°/2 = 90°. Here, that observation is described by ...
The angle at the circumference in a semicircle is a right angle
Answer:
(-1, 1), (-2, 2), and (-1, 3)
Step-by-step explanation:
The formula for rotation of a point (x,y) by an angle θ about the origin is
x' = xcosθ - ysinθ
y' = ycosθ + xsinθ
If θ = 90°, sinθ = 1 and cosθ = 0, and the formula becomes
x' = -y
y' = x
P: (1, 1) ⟶ (-1, 1)
Q:(2, 2) ⟶ (-2, 2)
R: (3, 1) ⟶ (-1, 3)
The vertices of P'Q'R' are (-1, 1), (-2, 2), and (-1, 3).
The Figure below shows the triangle before and after the rotation.
