Notice that you didn’t see the gray measurement label (the tool tip) since the tool tip is part of
the Smart Guides that you turned off. The magenta alignment guides are also not showing
since the shape is not snapping to other content on the artboard. Smart Guides can be useful in
certain situations, such as when more precision is necessary, and can be toggled on and off
when needed.
Click the Fill color box in the Properties panel, and make sure that the Swatches option ( ) is
selected in the panel that appears. Select a light gray color with a tool tip of “C=0 M=0 Y=0
K=30.”
Choose View > Smart Guides to turn them back on.
With the Polygon tool still selected, drag the side widget on the right side of the bounding box
to change the number of sides to three, making a triangle.
Drag a corner bounding point of the triangle until you see a width of 1.2 inches and a height of
0.8 inches in the measurement label.
