In our case, one leg is a base, and the other is the height, as there is a right angle between them. To find the area of the triangle, use the basic triangle area formula, which is area = base × height / 2. For this special angle of 45°, both of them are equal to √2/2. If you know trigonometry, you could use the properties of sine and cosine. Join Quizlet and master geometry in a fun and easy way. You can also test your knowledge with interactive quizzes and games.
