Question

what is the first step to analyze angles in a layout created with geogebra?
a. measure distances
b. select the angle tool
c. draw polygons
d. create parallel lines

an airplane travels from (0, 0) to (6, 8) in a straight line. what is the total distance traveled by the airplane?
a. 12 units
b. 100 units
c. 80 units
d. 10 units

Explanation:

Step1: Identify the first - question topic

To analyze angles in GeoGebra, we need the Angle tool.

Step2: Identify the second - question formula

Use the distance formula $d = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}$ for two points $(x_1,y_1)$ and $(x_2,y_2)$. Here, $(x_1,y_1)=(0,0)$ and $(x_2,y_2)=(6,8)$. So $d=\sqrt{(6 - 0)^2+(8 - 0)^2}=\sqrt{36 + 64}=\sqrt{100}=10$.

Answer:

1. b. Select the Angle tool
2. d. 10 units
