Unable to follow tutorial as directed

I’m on tutorial one and after I draw the 30mm X 40mm triangle none of the following steps are functioning correctly. Such as when I click on the triangles side the “make construction” option is supposed to be available but isn’t. Then the tutorial goes one to say to select the three circles it has the user draw by holding shift and click the circles that option won’t work. So forth and so on. So far I’ve tried to reinstall but to no avail. Any advice would be greatly appreciated.
