# Help with Construction (I am a beginner)

lackadaisical_lies shared this question 3 years ago

How would I construct a triangle with side lengths 4cm and 7cm with an included angle of 68 degrees? I know how to use the 'interval with a given length tool' but I don't know how to incorporate it with another interval at 68 degrees.

Any help would be appreciated! Thanks :)

You just need to do what you'd do with pencil and paper.

Here it's an easy step by step construction (other ways are possible...)

Here http://wiki.geogebra.org/en... you can find the GeoGebra tutorials.

I suggest you to have a look at the Quickstart and IntroBooks series, that contain nice hints about the basic features of GeoGebra.

Or you can work with two circles that have the same centre.

goodmorning.

here another solution

hello, I have been figuring out how to use geogebra to teach the concept that linear functions produce a straight line when plotted on the cartesian plane. I want to use a slider animation to show only the points being plotted which will help the learners get the idea (please look at the attachment)

define a sequence of points limited by a slider and defined by the parameters a and b and a hidden function f(x)=a x + b
